About us

Defacto Technologies is an innovative chip design software company providing breakthrough RTL platforms to enhance integration, verification and Signoff of IP cores and System on Chips. 

New segment markets such as automotive, mobile, virtual reality and artificial intelligence require leading edge SoCs with greater functionality, higher performance and much lower consumption. Meeting time-to-market requirements and lowering the overall cost including design steps is becoming a critical factor of success.

By adopting Defacto’s STAR design solutions, major semiconductor companies are continuously moving from traditional and painful SoC design tasks to the Defacto’s joint “Build & Signoff” design methodology. The related ROI has been proven for hundreds of projects. 

Best trade-off  

After a first success on moving traditional DFT checks to RTL, Defacto shifted its focus, 10 years ago, on providing SoC design solutions to help reaching aggressive PPA requirements cost-effectively. Defacto has proven the effectiveness of STAR as a design platform for large SoCs. 

Headquartered in the French Alps with a US branch in California, Defacto has today a worldwide presence with a 24/7 support all over the world.
