Dr. Vlach's parents remained in Waterloo, Ontario. Sadly, his mother Dagmar passed away in 1999. However, now 88 years old, Martin's father Jiri is still in Waterloo as an EE Professor Emeritus, and a fellow of IEEE. Remarkably, Jiri is working on an update edition to his last book, “Computer Methods for Circuit Analysis and Design.”

Career Prosperity

For the 15 years Martin served at Analogy, Inc., he was a member of its Board of Directors and as well as its Chief Scientist. He was instrumental in attracting substantial angel investment to Analogy prior to its successful 1997 IPO and subsequent acquisition for a cash price from Avant! announced in December 1999 as $24 million.

The Avant! purchase of Analogy closed in early 2000. (More than 10X the size of Analogy when the acquisition of Analogy occurred, Avant! was headquartered in Fremont, CA. Two years later, Avant! itself became part of Synopsys, Inc. in a controversial M&A deal that was announced in December 2001 and finally closed in June 2002 after a lengthy FTC review).

Dr. Vlach had departed from Avant! in 2001 to found Lynguent, many months before Synopsys tendered its first offer to acquire Avant!. (Martin was fortunate to have been completely absent from the subsequent Synopsys/Avant! situation, which involved lawsuits, insurance against acquisition failure, allegations of IP theft, and the FTC issues).

In the year prior to its acquisition by Avant!, Analogy had an employment of over 200 people and revenue of $28 million. At Analogy, Martin conceived of and architected both the SABER simulator
(A) and the MAST
(B) hardware description language (HDL), products which are still used worldwide by Synopsys customers to design a wide variety of systems, from complex mixed-signal (analog and digital) integrated circuits (ICs) to mixed technology consumer, automotive, and aerospace systems including electronic, hydraulic, mechanical, and optical components.

Lifelong Interests

His travels and residences throughout his 60 years in various parts of the world, have resulted in Dr. Vlach maintaining official citizenship in three countries (The US, Canada, and of course the Czech Republic). This circumstance provides Martin and Lynguent with multiple advantages. Martin also speaks 3 languages fluently (Czech, French and English), and he also has a reasonable ability to speak and understand some German, Russian, and Spanish). This of course helps explain his ongoing interest in language and linguistics. It also speaks to why Lynguent has such a funny name, and why he is especially sensitive to serve users that have special language

Dr. Vlach tries to maintain balance in his life by turning as frequently as possible to his love of skiing, mountain hiking and in recent years, snowboarding!

Martin's grown children are also accomplished, both with fine educations and diversified livelihoods. Daughter Claire is a graduate of Vassar with advanced degrees in both urban planning and urban design from the University of Michigan. Claire, now a resident of the San Francisco Bay Area, just succeeded at age 28 in having her very first professional design completed: the renovation of the Oakland Airport.

Two years his sister's junior and graduate of New York University (NYU), son Eric is an international professional dancer based in New York, and also serves as the IT expert for Lynguent.

Lynguent today

Martin's role in Lynguent, the subject company of this two-part EDA WEEKLY sequence, has been and of course remains pivotal. His selection of key technical and management personnel for Lynguent would naturally reflect his knowledge of colleagues and friends from his previous lifetime and his deep, successful start-up experience at Analogy. These include but are not limited to Barbara Bakken, Ernst Christen, Jim Holmes, Alan Mantooth, Eva Solarova, and many others.

Keeping in mind the
current management team at Lynguent, here are just some of the people besides Sam Young that Martin has brought into Lynguent in the past:


Dr. Alan Mantooth is a co-founder of Lynguent. He is also a professor in the Department of Electrical Engineering at the University of Arkansas and holds the 21st Century Chair in Mixed-Signal IC Design and CAD where he has directed over $20 million in externally funded research. He has over 20 years of experience developing models, and modeling methods and tools. He returned to academia in 1998 after eight years at Analogy (now a part of Synopsys, Inc.), where he directed a team of 10 engineers on modeling tool research. Alan holds three patents on software architecture for modeling and simulation tools and has published over 100 refereed articles on
models and modeling tools. He has developed semiconductor device models for MOSFETs, diodes, power diodes, IGBTs, SCRs, and most recently SiC diodes, SiC MOSFETs, SiC SITs and JFETs, and SiC thyristors. Martin Vlach says Alan influenced the early direction of Lynguent towards modeling, and away from debugging; worked out to be the better direction. Alan holds a Ph.D. from Georgia Tech.


Barbara Bakken is a co-founder of Lynguent. She brings over 20 years of business experience in managing projects, programs, and teams. Throughout her career she has sought out opportunities to work in all areas of running a business. Barbara has a diverse background that ranges from conducting market research, developing and delivering corporate training programs, and managing employee relations programs. From 1996 to 2004 Barbara managed Analogy's Saber Simulator (Analog/Mixed-Signal Simulation) research and development team through an IPO and subsequent acquisitions at by Avant! and Synopsis. She is a certified Project Management Professional (PMP)
from the Project Management Institute. Barbara holds a BA in Sociology from Humboldt State University and an MS in Industrial and Labor Relations Management (MILR) from the University of Oregon. Martin Vlach says Barbara joined His company on St. Martin's Day, which is November 11; one of his best St. Martin's day presents ever!


Jim Holmes joined Lynguent after 13 years at Texas Instruments, where he was an analog/mixed-signal system-on-chip (SoC) modeling and simulation specialist. While there he focused on validation and verification of over 40 SoCs, spanning consumer applications from servo control in hard disk drives to baseband processing in cellular phones. He supported AMS modeling activities worldwide at Texas Instruments' design centers, as well as its customer and contractor sites. He developed key modeling methods that unified specification, design, and test activities across the globe. In 2004, Jim was elected Senior Member Technical Staff at Texas Instruments.
Jim Holmes was an early user of Saber/MAST at TI, and Martin Vlach says he was delighted to get Jim on board at Lynguent when offered the chance. Jim currently leads Lynguent's research team that is commercializing an expert system for analog/mixed-signal model composition and analysis. He holds a BS and an MS in Electrical Engineering from the University of Connecticut.


Ernst Christen, before joining Lynguent, held leading positions at Analogy, Inc., Avant! Corporation, and Synopsys, Inc. working on mixed-signal simulation, modeling technology and language design. He was the principal investigator for two DARPA contracts in the area of analog and mixed-signal hardware description languages. As the vice-chair of the IEEE P1076.1 Working Group and a co-chair of its language design committee, Ernst has made major contributions to the definition of IEEE Std. 1076.1 (VHDL-AMS). He continues to serve as chair of this group. He was also the lead developer of SAE standard J2748 - VHDL-AMS Statistical Analysis Packages. Ernst
holds three patents and is the author of over 40 publications. His interests include hardware description languages and mixed-signal multi-technology simulation. Ernst received a Diploma in Electrical Engineering and the degree from the Swiss Federal Institute of Technology, Zurich, Switzerland, in 1975 and 1985, respectively. From 1985 to 1987, he was with the Department of Electrical Engineering, University of Waterloo in Ontario, Canada, as a postdoctoral fellow.

Martin Vlach met Ernst for the first time in 1976 when Martin's father was on sabbatical at ETH Zurich (Eidgenössischen Technischen Hochschule Zürich) and Ernst was a student there. Ernst eventually became a post-doc with Martin's father Jiri, and Ernst came to work for one year in 1987 at Analogy. Except for a brief hiatus when Ernst stayed with the SABER team at Synopsys, Ernst has been Martin's colleague the longest of any other. Ernst was also “adopted” by Martin's
young children as their “uncle” a long time ago; he's still an honorary member of the Vlach family.  


Eva Solarova has over 25 years of experience managing teams in architecture, specification, design, and implementation of information technology systems. She was head of the department of information technology at Czech Television until 2005. Eva also spent 2 years working in the Research Institute for Telecommunication and Electronics. Eva joined Lynguent s.r.o. Prague in 2006. She graduated from Charles University in Prague with degrees in Math and Physics.

Martin has also shown keen perception in associating Lynguent with outstanding individuals at the board and advisor levels. Space does not permit discussing the Lynguent Board of Directors or the Advisory Board here, but the current members of both are respectively listed with their backgrounds on the Lynguent web site at:


Each list includes the newest members mentioned earlier in this article.

Martin and of course Sam Young highly value the roles these two groups have played and will play going forward. Martin was very complimentary when speaking about the roles his directors and advisors have played. The writer specifically recalls Martin saying the following about
veteran Director Mr. L.B. Day. “Just after I started Lynguent, I ran into L.B. Day one day at an airport just by chance. (Of course I knew L.B. from years earlier at Analogy). I immediately told him about having started Lynguent and asked him straight out to be on the Lynguent board. L.B. did not hesitate and accepted on the spot! L.B. has been an excellent addition. He has been very influential in attracting other fine board members and many terrific advisors as well.”


Definitions of terms used in “Lynguent Parts I & II”

(A) SABER: Saber is a multi-domain modeling and simulation environment that enables full-system virtual prototyping for applications in analog/power electronics, electric power generation/conversion/distribution and mechatronics. Decades of industry success and innovation have earned SABER a reputation as the solution of choice for design validation and optimization for automotive, aerospace and industrial systems.


(B) MAST: The MAST Hardware Description Language (HDL) (now offered by Synopsys) is the defacto industry standard. First released in 1986, MAST is the most advanced modeling language (until Lynguent) available for analog, mixed-signal and mixed-technology applications. Until the advent of MAST, developing analog behavioral models was only within the realm of a few individuals - those with expertise in low-level simulator details and those with an in depth understanding of macro-modeling techniques. Today, MAST provides an analog methodology in which models can be created - and
maintained - by users as well as their IC suppliers, ASIC vendors or EDA tool providers.

The rich set of modeling constructs available in MAST allows a user to model both analog behavior and event-driven behavior as demonstrated in a pulse width modulator or a voltage comparator. This truly makes MAST a mixed-signal hardware description language. MAST allows a user to model complex electrical circuits quite efficiently. It also has a well-defined interface that allows access to C++ and FORTRAN routines from within a model, allowing ready reuse of existing models. Many models, like the BSIM models from UC Berkeley, the GaAs MESFET model from
Triquint Semiconductor, and numerous other proprietary MOSFET, MESFET and bipolar transistor models, have now been ported to MAST via this mechanism. MAST lets a user make extensive use of hierarchy when developing models, which further encourages model reuse. MAST also possesses many advanced features that allow a user to specify information like stress measures and statistical variations on parameters.


(C) Verilog HDL According to the EDA Glossary provided by the EDA CONSORTIUM website, Verilog HDL is one of two standardized hardware description languages used to specify the structure and behavior of electronic systems in textual format. Developed in the mid-1980s as a proprietary language and acquired by Cadence Design Systems, it became a de facto industry standard. In the mid-90s Cadence placed it into the public domain and it became a de jure standard promulgated by the Institute of Electric and Electronic Engineers (IEEE).
Verilog ® is also the name of a legacy simulation tool offered by Cadence.

(D) VHDL (VHSIC = Very-High-Speed Integrated Circuit) Hardware Description Language). Also according to the EDA Glossary provided by the EDA CONSORTIUM website, VHDL is the other one of two standardized hardware description languages used to specify the structure and behavior of electronic systems in textual format. Supports behavioral, register-transfer-level (RTL), and gate-level logic descriptions. Developed by the industry in the mid-1980s through funding by the U.S. Department of Defense, VHDL is also a de jure standard promulgated by the Institute of Electric and
Electronic Engineers (IEEE).

(E) SPICE (Simulation Program with Integrated Circuit Emphasis) Also according to the EDA Glossary provided by the EDA CONSORTIUM website, SPICE is an industry-standard
analog simulation language which contains models for most circuit elements and can handle complex nonlinear circuits. Also refers to a freely-distributed simulation tool which simulates circuitry described in the SPICE language. According to the website “All About EDA” by Simon Young, FastSPICE is one among several second generation circuit simulators that were born of necessity when custom, usually digitally-dominated, IC designs overtook the capacity and run-time capabilities of SPICE. Several innovations in EDA enabled Fast-SPICE simulators, yet their application isn't without some
limitations and care has to be taken in modeling and simulation both to ensure the results obtained are valid, according to Young.

advisory board. Hill is managing director of learning and organization development for Lam Research Corporation. His expertise is in leadership development and organizational effectiveness.


Starting with the initial EDA WEEKLY article posted on November 09, 2009, the first year's series of EDA WEEKLY articles by this writer continued on December 07, 2009, with the publication of an article entitled,
“MAD Progress.” It was the second of thirteen debut-year articles through October 2010, the thirteen issues a result of the schedule of publishing every four weeks:

One Year Later:

Below is a brief entry recently submitted by the
Mechanical Analysis Division of Mentor Graphics Corporation by invitation, as its entry in the
ONE YEAR LATER follow-up program initiated by the EDA WEEKLY writer on November 15, 2010:

Mentor Graphics Brings a New Perspective to Electronics Cooling Analysis

For the twelve months after its first appearance in Dr. Henke's EDA WEEKLY series, the
Mentor Graphics Mechanical Analysis Division has continued to serve the needs of flow and thermal analysis applications ranging from data center cooling to LED luminaire temperature measurements. The division's tools have proven to be well positioned to address emerging opportunities in green design, electronic design, automotive and aerospace applications, and more.

The Mentor Graphics FloTHERM software solution optimized for electronics cooling applications has become the leading computational fluid dynamics (CFD) thermal tool in the electronics vertical market.
Figure 1 illustrates a typical FloTHERM view depicting the heat flow paths from an IC device, from the silicon outward.

With the October 2010 announcement of
FloTHERM 9 , the software product gained capabilities that are unmatched by any other solution in the field. Innovative new post-processing features within FloTHERM now enable electronic device and system designers to understand why a design might be running too hot. Two newly-developed quantitative measures and displays help users visualize critical-and formerly invisible-thermal characteristics in their designs. The
Bottleneck (Bn) number identifies flow paths that exhibit high heat but at the same time, resist the flow of that heat. The
Shortcut (Sc) number reveals opportunities for alternate and more efficient heat flow paths; in other words, shortcuts for the heat.

Ultimately the Bn and Sc values add to the designer's understanding of the ease with which heat leaves a system, and then help him or her reconfigure heat flux distribution to improve performance. A redesign informed by the Bn and Sc data can do more than just recognize bottlenecks; it can also bypass them.

Figure 2 shows the results of such a Sc analysis. The Printed Circuit Board (PCB) has a large Ball Grid Array (BGA) processor device at its center, and a previous Bn characterization (not shown) has revealed the component to be an area of troublesome heat concentration. But the Sc view implies that an easy fix is available. The blue-to-red color gradation on the BGA is not a temperature reading; instead it indicates areas of more efficient heat conduction as expressed by the Sc values on the scale to the right (higher values are better). Heat is most inclined to travel up
through the top of the IC. A conventional heat sink is all that's needed to transport the heat away from the processor.

To cite a less elementary real-world example, FloTHERM 9 and Bn/Sc recently spared IC designers many weeks of iterative design attempts in the development of a new cell phone charger product. Engineers were able to model thermal vias, extended copper planes, and evaluate other approaches without having to wait for physical prototypes.

Heat density is increasing rapidly in almost every electronic application. The need for thermal tools that provide answers-not just data-is urgent. In the realm of IC and PCB design, the Mentor Graphics FloTHERM 9 breakthrough equips designers to quickly identify and solve thermal problems ranging from subtle to extreme.


Thanks go to out to Mentor Graphics' Ms. Suzanne Graham and Dr. Erich Buergel for their vignette to celebrate the EDA WEEKLY ONE YEAR LATER program.
