Semifore and Breker Partner to Deliver Seamless, Automated Portable Stimulus Flow

SAN JOSE, CA--(Marketwired - May 23, 2016) - Semifore, Inc., the leading developer of tools for the automation of the implementation of the hardware-software interface for ASIC, SoC and FPGA-based designs, and Breker Verification Systems, Inc., the System-on-Chip (SoC) Verification Company, today announced an integration of their solutions for SoC design and verification engineers. Immediately available, the integration allows easy, flexible design and specification of SoC control registers and automatic generation of portable stimulus and tests to verify the register implementation.

Semifore's CSRCompiler™ is the industry's most advanced and highly configurable hardware-software interface implementation tool designed to eliminate the gap between hardware design, software development and verification. The cornerstone of the CoStar (Configuration Status Register) Design Director™ platform, CSRCompiler generates a high quality RTL implementation; significantly enhances the verification team's performance by generating, from a single source, the register class instances based on the UVM register abstraction class library, including backdoor paths; and generates the necessary software header files for the software/firmware development team. With this new integration, CSRCompiler also generates intermediate files that are then imported into the Breker solution to create a graph-based scenario model of the registers.

Breker's Trek™ family of products and apps automatically generates multi-threaded test cases that verify SoC designs design more quickly and more thoroughly. These test cases are reusable from IP to full-chip level, and from simulation to silicon, meeting all requirements for the upcoming Accellera standard on Portable Stimulus. When the files generated by CSRCompiler are imported, portable stimulus can be generated to verify the registers in simulation, emulation, FPGA prototypes, and silicon. Current Breker users who specify their registers using the IP-XACT standard can import this definition into CSRCompiler directly or enhance it to the Semifore CSRSpec format to take advantage of more CSRCompiler features.

"This new integration provides a single flow for the design and verification of a complete SoC, starting with its architecturally defined registers," said Richard Weber, CEO of Semifore. "This satisfies our customers' request for a link between our advanced register specifications and their SoC verification process."

"Many of our customers have been frustrated by the limitations of IP-XACT for the specification of their control registers," stated Adnan Hamid, CEO of Breker. "With the advanced capabilities included in the CoStar Design Director platform, specifically the CSRSpec language and CSRCompiler, customers can now automatically generate test cases for the registers as the first step in SoC verification."


The new, integrated solution is available today.
