agilent eesof eda offers both single user software products as well as enterprise - level solutions .
vendor libraries: eesof had amassed a good following of parts vendors that would supply s - parameters in eesof' s platform – hence the
touchstone
file format - which lives on today .
for detailed information on each product, please refer to the keysight technologies eesof webpage at: urltoken .
eesof' s first software product was a high frequency linear circuit simulator called
touchstone
. the eesof touchstone program is said to have quickly become popular among many microwave circuit designers in the specialized marketplace of high frequency engineers. as a result, eesof began to realize a small but growing commercial revenue stream generated by touchstone. then in 1984, eesof independently decided to market links to the then - popular
eesof eda division of agilent technologies, located at 1400 fountain grove parkway, santa rosa ca, 94503 .
eda vendors! (moreover, the writer recently learned that agilent eesof eda has continued to flourish, and in 2009 agilent eesof revenues were approximately $ 120 million and the division' s worldwide employment surpasses 400) .
things were going well at eesof, and in december 1987, the company celebrated its first $ 1 million revenue month .
eesof
products such as touchstone, libra, and omnisys brought comparable power and ease of use to the pc platform .
as the detailed narrative of the 27 - year eesof evolution began to emerge, it soon became clear that accurate reporting would demand more than one issue of the eda weekly. the writer and the eesof team quickly recognized the historical cues that led to the following structure :
there were many other eesof - hp skirmishes with words and ads during the 1988 to 1993 period that went beyond mere product specs. some were relevant, others were not. for example, a few eesof folks at the time would occasionally challenge hp' s ultimate commitment to stay in the commercial rf / mw software market .
i think we put all questions to bed about our commitment when hp acquired eesof ,
agilent eesof eda describes itself these days as ,
the leading supplier of electronic design automation (eda) software for high - frequency and high - speed system, circuit, and modeling applications .
while agilent eesof' s financials have not been routinely published separately from those of the overall agilent electronic measurement group in which agilent eesof resides, the eda industry generally acknowledges agilent eesof' s market leadership position in annual revenue generation in its radio frequency (rf) niche (e. g. estimates are as high as 67% market share in 2009) .
prior to founding eesof, abronson was the president of amplica, a microwave amplifier company located in thousand oaks, ca. after amplica was purchased by comsat, abronson formed eesof and immediately hired childs from comsat to manage eesof' s r & d; efforts and to introduce a cad methodology. abronson and childs quickly hit upon the innovative value of offering personal design software to a market previously dominated by more expensive, server - based solutions .
eesof often ran ads that always showed food on top of a computer in a covert but successful effort to promote obesity and chair stains in the industry .
libra. ” this writer has been told on solid authority, that the technology behind libra was developed completely within eesof. some external reports have implied that libra came from the hp funded work that ken kundert and other hp employees commercialized from uc berkeley. this implication is patently untrue, say eesof veterans .
plott told the writer. “and today, seventeen years later, agilent eesof remains uniquely committed and out - invests any other vendor in this space. ”
part ii: a future eda weekly article on eesof will encompass the (a) post - merger years from1994 until the agilent technologies' spin - out from hewlett packard and subsequent ipo in 1999, as well as (b) the post spin - out years of rapid agilent eesof expansion from 2000 to 2010 .
randy rhea in the mid 1980’s, eagleware developed its niche serving smaller companies with a cost - effective, easy - to - use, circuit simulation and synthesis tool set. this part of the story will be more relevant in eda weekly part ii of the agilent eesof narrative, because eagleware would eventually join the agilent eesof team via acquisition. in fact, the former eagleware ceo ,
charles plott (product marketing & planning manager). this initial session was the first of several subsequent get - togethers over two elapsed weeks as the structure of the narrative of agilent eesof took shape .
omnisys, the first rf system - level simulator using block diagrams. for years, this was a competitive technical advantage for eesof. hp eventually introduced a system model library in mds to better balance the battlefield .
keysight technologies (eesof eda) is a set of designer tools for high - frequency system, circuit and modeling applications. under special agreement between keysight technologies and cmc, the following products are available to university clients :
in 1993, hewlett - packard acquired eesof (short for electrical engineering software), inc. , in westlake village, california, a recognized leader in eda software on the pc platform. beginning with the touchstone linear simulator in 1983 and adding libra, omnisys, and academy (for layout), eesof had focused on the rapidly expanding personal computer (pc) platform and on making eda tools available to every rf and microwave engineer .
many new competitive fronts between eesof and hp emerged during this 5 - year period. it was a time during which both organizations were independently focused in a commercial battle for mindshare among the world' s rf / mw designers .
the period from 1993 onward was a substantial growth period for the hp eesof organization, with multiple technology innovations, acquisitions, partnerships, and expansions into new markets. these will be the subjects of part ii in this series .
pc vs. unix: eesof clearly had the better pc offering, whereas the hp software was developed predominately for unix. that said, at the time hp had the advantage of being a supplier of both the software and the workstation .
keysight eeda has been training engineers for many years and has perfected the process. a combination of lectures and labs provides hands - on practical experience in an accelerated learning environment. for more information, refer to keysight eesof eda customer education and services .
westlake village, california, usa - keysight eda continues the strong tradition of user - interface and circuit and simulation advances that were begun by eesof, inc. located in southern california, westlake village is about 45 miles (70 km) northwest of los angeles .
jake egbert, now retired, was the gm on the hp side and he led the combined entity for the next seven years. post hp acquisition, chuck abronson didn' t stay long at eesof, but bill childs helped during the critical transition period for about a year .
sonnet (and the current, combined agilent eesof eda organization still does). but both vendors also decided that it was strategically important to develop their own respective in - house technologies that could be natively integrated into their own platforms. hp had a first - to - market advantage with its
agilent eesof eda provides its customers a broad spectrum of eda software, including applications for microwave (mw), radio frequency (rf), high - frequency, high - speed, rf system, electronic system level (esl), circuit, 3 - d electromagnetic, physical design and device - modeling .
among the hp internally developed software tools of that era was hp' s own highly capable netlist - driven linear simulator (named ‘mantis’ within hp). there was also a short period wherein hp began to oem the touchstone product from eesof, but this business arrangement didn’t last long, given what was on the hp horizon .
as part of their university educational support program, keysight offers students and instructors access to licenses for many of their electronic engineering software (eesof), including ads, systemvue, genesys, ic - cap, empro, and goldengate. use of the software is for educational purposes only, and not for commercial gain or research .
one of my first assignments at eesof in 1984 was to develop the industry' s first interface from a circuit simulator to the recently introduced 8510 network analyzer from hewlett packard ,
larry lerner said .
this early experiment validated a critical design and verification methodology that has improved how rf engineers do their work to this day .
plott. “even today, in some of the markets we serve, we have smaller competitors that try to lure agilent eesof eda back to the pre - 1993 competitively - focused culture. we’re not going back. as long as we stay focused on innovating solutions to our customers’ tough problems, competition seems to work itself out in the long run ,
plott asserted .
chuck abronson first called the executive leadership of hp, to explore hp’s willingness to sell off its software group. however, internal to hp, this software group had not only become strategic to hp’s overall portfolio, but also it was growing rapidly – so there was understandably not a lot of hp interest in abronson' s overture. that’s when the conversation turned to the reverse possibility of hp acquiring eesof .
keysight eesof eda is the leading supplier of electronic design automation (eda) software for communications product design. microwave and rf circuit, high - speed, device modeling, and signal - processing design engineers accelerate the development of better products using design flows built on our device modeling, electro - thermal, electromagnetic, circuit and system design and simulation tools. keysight eda applications support the commercial wireless, aerospace and defense industries .
advanced design system (ads) is the flagship product from keysight eesof eda, the technology and innovation leader in high - frequency, mixed - signal electronic design automation (eda). it is the only design simulation platform that enables the co - design of ic, package and board in high - frequency and hi - speed applications. ads seamlessly integrates system, circuit, and full 3d electromagnetic simulation with keysight’s test instrumentation to perform single pass successful electronic designs repeatedly .
the immediate aftermath of the merger became an interesting time for the newly - combined business. for years eesof and hp had been essentially focused on each other and the cultures at both companies had been predominately competitive. with the merger in 1993, the mood is said to have instantly changed .
this marked a period where we had to make a fundamental alteration in our organization. without each other to focus on, we shifted much more attention to our customers' successes ,
said
meanwhile during the 1980s, some other folks were working on applying maxwell' s equations to solve arbitrary two and three dimensional geometries. sonnet was among the first of these software products. james rautio started sonnet in his home in 1983, while designing mmics for general electric in syracuse, jumping ship in 1988 and making his first sale the following year. sonnet is still privately held, unlike super compact, eesof, or eagleware. learn more about the early days of sonnet here on their web site .
electromagnetic professional (empro) is keysight eesof eda' s electromagnetic (em) simulation software design platform for analyzing the 3d em effects of components such as high - speed and rf ic packages, bondwires, antennas, on - chip and off - chip embedded passives and pcb interconnects. empro em simulation software features a modern design, simulation and analysis environment, high capacity simulation technologies and integration with the industry’s leading rf and microwave circuit design environment, advanced design system (ads) for fast and efficient rf and microwave circuit design .
santanu roy february 08, 2010 reviewed by' santanu roy' enjoyed the article. i worked in australia back in the late 80s and we had touchstone and academy later. thoroughly loved using them for microwave circuit design (amplifiers and passive circuits). still used to use rubylith then and had to buy that silly diamond head cutter and ruby from the states. used to have a great time with the eesof team writing bug reports (even visted eesof once when back packing trip from australia - very nerdy! !). when series 4 came it was hard to get used to but we used it (altghough i seemed to remember many did not make the switch and kept the older versions) - microwave engineers getting angry at sw - now there' s a sight. we had eagleware also but used it for the filter synthesis tool now i use awr at work but i am evaluating ads - ads is the best! !! ! love it (and i have used ansoft also)! !! ! still learning lots and still enjoy circuit design even after 20 years. 30 of 31 found this review helpful. was this review helpful to you?

comsat could read the writing on the wall and eventually offered super - compact - pc, a version of which could run on an ibm pc. they added their own layout tool, auto - art. however, supercompact pc was a
chopped - up
version of the large mainframe program, while touchstone was written for the pc architecture, taking advantage of the new operating system, and the decade - long leadership of compact software was successfully challenged by eesof. after comsat lost interest in cad, compact software again became a private company, owned by ulrich rohde. it was located across the street from his other microwave enterprise, synergy microwave, in beautiful patterson nj, birthplace of funnyman lou costello .
compact was bought out by comsat in 1980, and les besser was associated with it for three more years only. during that time a third - generation version, supercompact was released that became the industry standard. while the compact software group was fat, dumb and happy, a revolution started in the early 1980s, due to the ibm personal computer. even with its incredibly limited memory and low speed, some visionaries recognized that microwave design would some day be done on this type of platform. two specific groups of visionaries included some california dudes from
the valley
, who chose the name eesof, and some guys located at stone mountain georgia (near dogpatch), who chose the really cool name circuit busters (who ya gonna call? )
i can add a little background to the touchstone story. i worked at amplica during the period of time when eesof was formed. our president chuck a. had sold the company to comsat the year before i joined; comsat had also bought compact software the year before that. one of the comsat engineers that had worked with the compact part of the business (bill childs) was transferred to amplica to help develop our amplifier designs. it was bill who authored touchstone. he would carry a compaq portable pc back and forth to work every day (it looked like a sewing machine in its case), and thatâ€™s the platform he developed much of the code on. chuck was the money and business man, he made no technical contributions to the program .
to analyze circuits using touchstone, you had to have two display screens for your pc, one for handling the netlist and the other for displaying results. one huge innovation they are credited with is the ability to
tune
the circuit and watch the response move. touchstone required a hardware key on the printer port to keep track of the license, making it portable as well. by 1987 eesof' s touchstone was linked with a crude layout tool (micad), and a version of spice. another cool program they offered was anacat, which allowed you to control a hewlett packard 8510 network analyzer or the equivalent wiltron ana from a pc, and be able to sort data in an acceptable format for reading into touchstone. by this time the guys at compact must have soiled themselves with fear for their jobs .
eesof was a well financed enterprise from the beginning, the brainchild of chuck abronson and a former compact employee, bill childs. their first product was called touchstone, introduced in 1983. we don' t think the name was an acronym. to the user, it seemed like they had ripped off the entire compact netlist interface, but behind that they had created an entirely new engine (another hardware term unfortunately ripped off by geeks). it must have been very efficient, because it ran fast enough on an ibm - at pc so that it wasn' t too annoying (no doubt you had to spring for the math coprocessor on the pc). it also could run on h - p minicomputers. this quickly got a lot of attention from engineers who were sick of mainframes, where they generally had to play second fiddles to accounting and data processing departments .
peoples republic of eda cafe? february 06, 2010 reviewed by' chairman mao' i can only guess that my review will not be posted... or not for very long anyways... . what is wrong with this website? it seems that if anyone has a different viewpoint from the author they get their opinions deleted. this is why john cooley is the best source of information on eda tools at deepchip. com. he is the only one that allows users to strike back when eda companies and pr people try to make lies about eda tools. i cannot believe such a story about eesof. i use other eda tools in japan, but it is not a competitor... yet this story seems like a fable not a true perspective. anyway... i will not waste time writing my opinion anymore since the editors just delete what they do not like. 28 of 47 found this review helpful. was this review helpful to you?

this was les besser' s precursor to compact. in his own words :
speedy is not an acronym, we just wanted to advertise its speed, compared to the early day time - domain simulators that operated at low frequencies .
the second - generation program, compact, had circuit - optimization and it was commercially introduced through six different timeshare companies. its transistor databank, in addition to the fairchild products, also included other manufacturers' devices. in - house installations began in 1973, with communication research center (crc) of canada being the first one. see more on compact below .
according to robert p. (bob) coats, one of the first cad tool for microwave circuits, cain - 01, was developed about 1971 for use by designers at texas instruments. cain - 01 was available on an ibm 360 computer and accessed using punched cards. it was never marketed by the corporation. here we quote bob' s historical perspective on this achievement :
cain - 01 stands for
computer aided integrated networks version 1
. in july 1973 i published a paper in the july issue of the mtt transactions of the ieee. i used the software on the work described, and referenced an article by its designers. the authors were t. w. houston, l. w. dyer, and g. j. policky. the paper was entitled
computer - aided design of microwave integrated circuits
and it was published in the august 1969 ieee wescon convention record. the software was developed initially in support of the first phased array development program at texas instruments (the mera program). the software was widely used by microwave circuit designers at ti for many years .
for a while in the 80' s i had a program called
cadec
that ran on a hp 9845 desktop. it was stored on a hp - 200 tape cassette and did ok with passive circuits. it relied mostly on abcd parameters and z / y matrix analysis (like in low frequency ac circuit analysis with matrices). the cool part was it came in rocky mountain basic and you could go in and change anything, add new circuit elements, and mess around with display options. at the time martin marietta was strongly opposed to pc' s due to a very entrenched computer department, and we would order hp computers as
instrument controllers
so we could get some free computing power. i may still have a manual around .
for most of us, in the beginning, there was compact. the acronym stands for
computer optimization of microwave passive and active circuits
. introduced in 1973, it was the only commercially - available microwave circuit optimization software product available during the disco years (in - house programs at general electric and texas instruments were capable of analysis without optimization, see above). during the hippy epoch and for all times before, microwave design was done using a smith chart and a pencil and even the simplest designs took many months to develop. les besser was the originator of the compact program, and appears in our microwave hall of fame for laying the groundwork for microwave cad industry. les is a hungarian - canadian - american. born and raised in hungary, he escaped to the west in 1956, became a canadian citizen in 1961, later moved to the u. s. a. and was naturalized to usa citizenship in 2000. welcome aboard !
les besser submitted a description of his compact computer program to the ieee circuit theory transaction for publication in 1972, but they rejected it, perhaps because it didn' t contain enough fancy equations... below les besser fills us on this chapter of microwave history in an email to microwaves101 dated september 1, 2004 :
the article you mentioned was initially rejected by the ieee circuit theory (now circuits and systems) group. i felt quite bad at first, until i found out that phil smith' s original article on the smith chart was also rejected with
no practical contribution
comment. after rewriting the compact article (removing most of the explanations and adding lots of complex matrix equations) it was published .
the 201 mclean boulevard patterson location on route 20 near the river is and was a nice location and compact was in a fancy building. no need to shoot at patterson
when i bought the company from comsat, both the main frame version and the pc version where unstable and models such as t - junctions, crosses and others fairly inaccurate at higher frequencies. becoming a partner in the darpa mimic program, and mostly financed from earnings rather the darpa money, these things were changed by developing em - based models, and verified by raytheon and texas instruments .
n - dimensional nodal noise analysis for all types of both linear and nonlinear circuits, including oscillators, mixers and amplifiers under large signal conditions .
em - based models with extremely short computational time replacing lookup tables and curve fittings. the multi - coupled line model by itself is a full em - based simulator with extreme accuracy .
the first complete nodal - based harmonic balance simulator with the most stable convergence for multi - tone analysis, and still the leading approach in the industry. this is important for mixers (3 - tones) and n - stage designs where more harmonics are generated .
complete nonlinear microwave nonlinear models, much improved over the spice - type models, and new important models such as gaas, hbt (even physics based) and others became available .
a new yield analysis capability was added and other improvements in optimization (nonlinear optimization) were made. as an important example, oscillators can be optimized for best phase .
there were a large number of other enhancements made and utility programs added. after the merger with ansoft, the harmonica program became ansoft designer .
ulrich l. rohde, phd, ex - president compact software, chairman of synergy microwave company .
did we mention that ulrich was on the ansoft board of directors in 2004? ulrich had a few other comments but they they sounded too much like free advertising for ansoft so we cropped them out. one part of the original compact, smith tool, is rumored to exist in an ansoft program even today .
at one time, there was a version of compact that could be run as a module on the hp41 programmable calculator, so you could take your designs to the
reading room
. thanks to dave, who still has a copy !
we need to add some history here, but for now we' ll just copy some stuff we grabbed from the ansoft web site. ansoft was founded in pittsburgh pennsylvania in 1984 by dr. zoltan cendes. at some point they merged with supercompact .
attention intel and other politically correct companies... the word
bastard
is not a
swear word
, it means illegitimate. did you know that bastards are a fast growing demographic in the good' ol diverse usa? just ask your kids or grandkids how many of their little friends have parents that never married. maybe someday the ieee will form an interest group called
microwave transactions from bastards
, or mtb for short !
in case you are looking for mr. abronson, he' s now chairman of cap wireless .
circuit busters (what' s with all the capital letters that were used in the 1980s ?), was founded in 1985, by a filter designer randy rhea. while his team was at the task of developing a competing product for linear analysis, they put together some filter synthesis software. the first product was called star and you could buy it from a little ad in the back pages of trade mags for $ 99 (and they took visa and mastercard, another brilliant move not anticipated by compact), delivered on a 5. 5 inch floppy disc. this was truly an unheard of price, probably less than the square - root of what compact was selling for. we asked randy about this, and he recalled that he had to rethink the original price, considering the limited market. circuit - busters
second generation
product was called super - star and was marketed at $ 595 less than two years later .
since circuit busters was a garage shop, they didn' t get around to putting a key on the software until future versions. either they had some financial help from their in - laws, or they didn' t quit their day jobs for a few years. below is the earliest advertisement we could turn up for circuit busters (mw & rf january 1987), featuring an earnest - looking and young randy rhea (nice tie !), who personally guarantees his software. the unknown editor liked the price, and still has a copy of super star 1. 0 somewhere under a pile of other priceless artifacts !
what happened to circuit busters? they renamed the company eagleware in 1991, and they are a huge success (ask any of their well - treated employees !) eagleware is an inspiration to microwave garage operations all over the world, such as a certain microwave web site. in 2005, eagleware sold out to agilent. time will tell if the eagleware linear simulator survives, it certainly undermines the sales of ads. as paul harvey might say ,
now you know the rrreeest of the story !
a relative newcomer to microwave cad is applied wave research. this company was founded by a couple of ex - hughes mmic designers, well before raytheon bought hughes and deep - sixed their gallium arsenide operations foundry. in any case, awr' s microwave office is a slick package that combines a linear simulator with e - m analysis. they even allow you to plug in em software from their competitors, such as sonnet. interoperability is the name of the game going forward, these dudes know what they are doing .
here' s your opportunity to help us, there are other software products out there that we' d like to know the history of .
in 1992, zeland software started offering ie3d, in competition with ansoft' s hfss .
the first nonlinear simulators (besides spice products) also arrived in the late 1980s, and used harmonic balance techniques .
today, there is huge competition from software vendors for your microwave analysis budget. enjoy it! we' ll add more history of microwave software later, especially if some more of you
founding fathers
contribute !

the ever increasing data rates in high speed digital circuit boards and chips. beyond pure rf and microwave applications, agilent' s eda technology is also helping signal integrity engineers deal with the complex issues created by these high speed data rates. indeed, without such software design & analysis tools, high data rates can often lead to electronic systems that do not work at all .
designcon® conference & exhibition is just around the corner, scheduled for february 1 - 4, 2010 at the santa clara, ca convention center .
designcon is widely acknowledged as the definitive event for electronic design experts spanning chip, package, board, and system domains, addressing common issues in signal integrity, power management, interconnection, and design verification .
one unique aspect about this eda organization is that its software is also used internally by hundreds of agilent rf / mw engineers to help analyze and design most of agilent' s commercially - offered test and measurement equipment .
no doubt software is critically important, but at some point you actually need to build a circuit. agilent, and prior to that hp, has always seen a strategic link between eda and actual physical measurement. we often share algorithms, use models, and innovations across platforms – whether in the eda or in the measurement world
, said
plott .
whether measuring or simulating s - parameters in linear circuits, or x - parameters [ 1 ] in nonlinear circuits, we believe both software and test equipment are critical parts of a designer' s tool box .

, the first available version of spice with active, passive and distributed circuit models that permitted spice to be used effectively at high frequencies. (spice is an acronym for simulation program with integrated circuit emphasis and is a general - purpose analog electronic circuit simulator. now 37 years old, spice was first developed at the university of california at berkeley, and announced in 1973. later versions of spice are still widely used today in ic and board - level design to predict circuit behavior. by 1985 spice had become a standard computer program
anacat, a computer - aided testing tool that could import experimental test results directly into the software simulation environment .
hewlett packard company (hp) was internally developing solely for its own use, very capable software tools for analyzing and designing high performance instrumentation .
to give its hardware businesses performance and time - to - market advantages over competition. such software tools for the most part were not then available commercially. moreover, even if similar tools were commercially available from other suppliers, many manufacturing managers back then still believed that by using their own internally - developed proprietary software, they gained extra, unique advantages .
for by 1987, folks who were at hp at that time have told the writer that several business plans and product specification documents were circulating internally within hp. at this point it was clear that hp was committed to building up its
computer - aided engineering (cae) organization to enter the commercial eda market. from the original business plans, one key motivation of hp to ‘go commercial' was the desire by hp to provide a complete portfolio to all rf / mw r & d; designers – i. e. both software and measurement. this fundamental business driver remains in effect today .
beyond hp’s linear simulator, two additional important developments were also underway on the hp side. first was the development of a complete schematic capture interface with graphical layout and back - annotation – a major change to the older netlist approaches being used previously. the second was the result of research that hp funded at uc berkeley, where an hp employee named ken kundert and others within hp developed the first nonlinear, frequency domain simulator (harmonic balance). with the linear simulator, the design framework, the new nonlinear simulator and the required models, hp
eagleware (formerly named chip busters in earlier days) was also quietly building up a large following in another segment of the market. founded by
academy, a front - end schematic capture user interface for both touchstone and libra .
hfss. hp sent a project manager to pittsburgh to help manage the project and bring the original hfss product to market. hp introduced this product on the cover of the february 1990 issue of microwave journal .
momentum product, which came to market in 1992. (over the next 18 years, as
momentum advanced, it became one of the most successful and trusted em technologies in the market) .
hp impulse, the first convolution time - domain simulator that allowed the accurate inclusion of frequency domain models to help neutralize this part of the battlefield .
by this point both companies had grown to be about the same size, at approximately $ 20 million each in annual revenue. (the newly merged entity was estimated to be at just over $ 40 million in 1994 revenue) .
once merged, the two companies jointly marketed a combined and rationalized portfolio of simulation and analysis tools worldwide, eventually providing design solutions for applications including cellular telephones, wireless lans, collision - avoidance radar, defense electronics and satellite communications links .

embarrassed february 08, 2010 reviewed by' i' m embarrassed' i' m personally embarrassed by chris' response and similar rhetoric from others @ corporate. take a look at cooley' s anonymous tip. guess where it comes from. we don' t need to stoop to this kind of behavior. we have a good product. why can' t we compete on that. i don' t believe what i' m told from above. most of us don' t. all this whining and hate reflects badly on the us and badly on me personally. at least agilent has standards they try to live up to. i wish we has the same. 34 of 39 found this review helpful. was this review helpful to you?

think before you post february 08, 2010 reviewed by' rational engineer' i enjoyed your article russ. also, it’s probably not what was intended, but i think awr’s response above says more about their company than it does about their competitor featured in your interview. you’ve got to wonder if this is the tone and culture sponsored from the ceo on down. that would never fly in my company. so i guess i would say that i’m indeed influenced by the awr response, but probably not in the way they intended for me to be. 35 of 38 found this review helpful. was this review helpful to you?
