A system and method processor testing using test pattern re-execution is presented. A processor re-executes test patterns using different timing scenarios in order to reduce test pattern build time and increase system test coverage. The invention described herein varies initial states of a processor's memory (cache, TLB, SLB, etc.) that, in turn, varies the timing scenarios when re-executing test patterns. By re-executing the test patterns instead of rebuilding new test patterns, verification quality is improved since more time is available for execution, verification and validation. In addition, since the test patterns result in the same final state, the invention described herein also simplifies error checking.
