Semifore Inc. is a privately held Delaware corporation founded in 2006 and headquartered in Mountain View California.

We founded this company because we had written register management scripts for complex designs for more than a decade. We turned our expertise and passion for this problem into a new compiler-based tool that would be useful for many companies.

Semifore offers products and services for the specification and design of hardware and embedded software; we specialize in control register and address map specification and management. Our products significantly reduce the time and errors involved in developing and maintaining hardware, software, and design specifications. Keeping the address map information in sync across the multi-disciplinary design teams is now required in order to deliver system on a chip integration. We are committed to providing a consistently high level of service for our customers worldwide.

We support a variety of startup and established design teams who are developing a variety of IP cores, SOC’s, ASICs and FPGA’s. We have customers using our products to design successful projects  throughout the United States and Europe.

The company’s primary product is CSRCompiler™ which is a third generation control register and address map management tool. We support several input formats such as IP-XACT, SystemRDL, and CSRSpec.  CSRCompiler also supports advanced functions such as hierarchical address map specification, reusable templates and object orientation. We are proficient with the following technologies:

• Digital ASIC design
• Verilog & VHDL design and verification
• XML schema validation
• FrameMaker
