Abstract
A system and corresponding method perform verification. The system comprises a verification checker that monitors protocol messages of a coherency protocol. The coherency protocol is implemented via register-transfer level (RTL) logic of a chip to maintain cache coherency on the chip. The protocol messages are generated via the RTL logic. The system further comprises at least one memory. The verification checker performs verification of the coherency protocol based on system state stored in the at least one memory. The verification performed includes updating the system state based on the protocol messages monitored and controlling timing for the updating based on message classes. The message classes are associated with the protocol messages monitored. The verification checker reduces the likelihood that a processor design will have data inconsistency issues and can reduce time-to-market as verification implemented via the verification checker can make the verification effort more efficient.
