The Design and Verification Conference (DVCon) and Exhibition provides attendees with the industry’s most comprehensive technical program focused on the design and verification of electronic systems. DVCon attracts engineers and industry technologists across many design disciplines including systems, standard IC, ASIC, DSP, microprocessor, FPGA, library, analog/mixed-signal and SoC.


“Rich Weber is the go to guy for all things RTL. His experience and translation of RTL and specifications has enabled Semifore to build a compiler that is being used in a variety of applications by tier one customers. I believe companies would be well advised to take a look.”

Jim Hogan, Vista Ventures, LLC

Keeping up with a fast-moving, ever changing design can be hard for a verification team. Using CSRCompiler my team has been able to increase the quality of our design verification and continue to react quickly and effectively to the needs of our most demanding, fast-paced customers, as well as win new high-value deals for us and our shareholders.

Semifore was founded in 2006 and is an on-going healthy company that offers an advanced compiler for specification, verification, documentation, and implementation of configuration, status registers and address maps for complex designs. Semifore is self-funded, profitable, and with a healthy list of customers that include a significant number of tier 1 companies. It is clear that niche companies can still find a way to contribute to EDA and in the process generate a respectable revenue stream.
