Cache coherence formal verification

WebIn a multi-processor system, a cache coherence protocol is vital to maintaining data consistency between local caches and the main memory. With the local processor cache, the bus stimulus must be compliant with the cacheline state in the local cache, and must follow predefined ordering rules between the read/write and cache snoop stimulus ...
