Startups + technology strategy

I was founder or first European employee of six EDA start-ups in the US and UK. All six were successfully acquired, for a total of over a billion US dollars in 2026 money.

Company My role Acquired by
Gateway Design Automation (Verilog) First European employee, European Technical Manager Cadence, 1989
Chronologic Simulation (VCS) Vice President and European General Manager Viewlogic, 1994
Virtual Chips (silicon IP) Vice President and European General Manager Phoenix Technologies, 1996
Ambit Design Systems (synthesis) Vice President and European General Manager Cadence, 1998, $280M
Co-Design Automation (Superlog, SystemVerilog) Co-founder, President, CEO and Chairman Synopsys, 2002, $36M
Imperas Software (processor models, RISC-V verification) Founder, CEO and Chairman Synopsys, 2023

What those companies taught me

Many of the hard decisions in those companies were commercial: which market to enter first, when an open standard would help more than a proprietary product, and how a small company works with customers and partners many times its size. At Co-Design we took the Superlog language through Accellera, where it became SystemVerilog. At Imperas we built an ecosystem around open APIs and standards, first Open Virtual Platforms (OVP) and later the RISC-V Verification Interface (RVVI). In 2008 I led a management buy-out of Imperas; when Synopsys acquired it in 2023, it was owned by its staff and profitable.

Where EDA start-ups can win now

Agentic AI is where most new EDA start-ups are today. Most of them optimise existing workflows, and the large EDA vendors, and the largest chip companies building AI tools for their own use, are doing the same with far greater resources. The larger opportunity is a holistic approach that rethinks the toolchain itself, so AI can reason across design, verification and implementation. Start-ups aiming for step-function improvements of that kind need investors prepared to fund them on that basis.

I advise a small number of founders, boards and investors. See Strategy & Startups.
