摘要
A system and method for modifying a simulation model and optimizing an application program to produce valid hardware-identified operating conditions that are matched with simulator-identified operating conditions in order to modify a simulator accordingly is presented. A critical path coverage analyzer includes critical path measurement logic into a simulation model that injects errors into the critical path and provides visibility into the number of times that an application program exercises the critical path. The critical path coverage analyzer uses the critical path measurement logic to optimize an application program to adequately exercise and test the critical paths. Once optimized, the critical path coverage analyzer runs the optimized application program on a hardware device to produce hardware-identified operating conditions. The hardware-identified operating conditions are matched against simulator-identified operating conditions. When discrepancies exist, the simulator is modified accordingly to match the hardware-identified operating conditions.
