Abstract:
A cache purge simulation system includes a device under test with a cache skip switch. A first cache skip switch includes a configurable state register to indicate whether all of an associated cache is purged upon receipt of a cache purge instruction from a verification system or whether a physical partition that is smaller than the associated cache is purged upon receipt of the cache purge instruction from the verification system. A second cache skip switch includes a configurable start address register comprising a start address that indicates a beginning storage location of a physical partition of an associated cache and a configurable stop address register comprising a stop address that indicates a ending storage location of the physical partition of the associated cache.
