PLD Industry Perspective – New and Intriguing Player Entering the Ring.

"What makes Tabula a company to watch is that in addition to being founded by electronic design automation (EDA) guru Steve Teig, most of the executive team are former elite Xilinx employees including the highly-regarded CEO Dennis Segers. Mr.Segers' team is not to be underestimated."
By Hans Mosesmann

Dennis Segers  

Dennis Segers, CEO

Dennis Segers joined Tabula in May 2006 after serving as an independent board member for two years. Prior to Tabula he served as president, CEO, and director of Matrix Semiconductor. Matrix pioneered the design and development of three-dimensional integrated circuits, a first in the history of semiconductor technology. At Matrix, Dennis oversaw the transition of the company from the early technology feasibility phase to high volume production, culminating in the acquisition of the company by SanDisk in January 2006.

Previously, Dennis served as the senior vice president and general manager of the FPGA product groups at Xilinx. He oversaw the development and introduction of the Virtex family of field-programmable gate arrays (FPGAs), the most successful programmable logic family in the industry's history. Under his direction the high end FPGA division grew from a $300M business to over $1.4B. In April 2000 he was elected to the Xilinx board of directors.

A 35 year veteran of the semiconductor industry, Dennis has served as a board member and advisor to numerous venture capital backed startups as well as private and public companies. Dennis is currently a director for Parade Technologies, Ltd., a public fabless semiconductor company. A past member of the board of directors of the Global Semiconductor Alliance, Dennis also served as the Chairman of the GSA Emerging Company CEO Council from 2007 until 2010.

A graduate of Texas A&M University, he now serves as a member of the College of Engineering Advisory Board, and was a 2008 Outstanding Alumni Award recipient.

Steve Teig  

Steve Teig, President and CTO

Steve Teig is the President and Chief Technology Officer of Tabula and the inventor of Tabula's Spacetime 3-Dimensional Programmable Logic Architecture. In 2012, Tabula has been recognized with an Edison Award, an American Business Gold Award, inclusion in MIT's "TR50" list of the 50 most innovative companies worldwide, and as #3 in the Wall Street Journal's "Next Big Thing" list of the most promising venture-backed startup companies. Prior to founding Tabula, Steve Teig was CTO of Cadence Design Systems (NSDQ:CDNS). Steve joined Cadence through its acquisition of Simplex Solutions (NSDQ: SPLX), where he was also CTO. At Simplex, Steve invented and led the technology development for the X Architecture, which radically improves chip design by pervasively incorporating diagonal wiring.

Before joining Simplex, Steve co-founded two successful biotechnology companies: CombiChem (NSDQ: CCHM, later acquired by DuPont Pharmaceuticals), where he was CTO, and BioCAD, where he was CTO and, later, CEO. At CombiChem, Steve invented and led the development of the company's revolutionary Discovery Engine technology, with which CombiChem discovered pharmaceutical-lead compounds for 11 different therapeutic areas in only five years. At BioCAD, Steve designed Catalyst: market-leading software for pharmaceutical discovery.

In the 1980s, Steve spent several years in the EDA industry, where his work had a major impact still felt today. First, at Trilogy Systems, he invented the now-universal technique of compiled-code logic simulation. Then, as CTO and co-founder of Tangent Systems (which later became Cadence's very first acquisition), he invented the principal place-and-route algorithms for the Tancell and Tangate products. These techniques formed the core of Cadence's Gate Ensemble, Cell-3 Ensemble, and Silicon Ensemble systems and lay many of the foundations for the physical design of even today's chips.

Steve received a B.S.E. in Electrical Engineering and Computer Science from Princeton University. He holds over 240 patents. In 2002, he broke Thomas Edison's record for the number of patents filed by an individual in a single year. In 2011, he was awarded the World Technology Award for IT hardware innovation.

Alain Bismuth  

Alain Bismuth, Sr. Vice President, Chief Marketing Officer

Prior to joining Tabula, Alain Bismuth, a 25-year veteran of the semiconductor industry, was vice president of Altera's HardCopy product group. In this role he launched the HardCopy product line, the most successful line of structured ASIC products to date.

Alain also led the definition and launch of Altera's Cyclone FPGA family, the world's first true low-cost FPGA product targeting high-volume consumer applications.

Before joining Altera, Alain was at LSI Logic for almost 10 years, where he held various senior marketing and sales management positions. He led LSI Logic's European sales organization in the computer and consumer segments, and moved to LSI Logic's headquarters in Milpitas, California in the mid-1990's. There he led the team that introduced the world's first integrated DVD player/decoder chip and gave LSI Logic the top market-share position in this market.

Alain started his career as a product engineer at IBM Semiconductor. Alain received an M.S.E.E. from Ecole Centrale, Lyon, France, and a Master of Sciences in solid-state physics from Universite Claude Bernard, Lyon, France.
