The architectural complexity of advanced storage controllers has increased to a point at which architectural verification methods based on document inspections and reviews are no longer effective. To facilitate the architectural verification process, a high-performance simulator (TurboSim) has been developed for architectural-level verification. The TurboSim application includes a set of architectural-level models, which represent essential architectural components, and an automatic test case generator (ATG). The TurboSim ATG is used to generate realistic representations of customer direct access storage device (DASD) track data. The track data are used to drive different TurboSim simulation scenarios. After demonstrating its effectiveness as an architectural verification tool, TurboSim was enhanced to support the automatic generation of hardware test cases. These hardware test cases are used to ensure that the hardware implementation matches architectural specifications.
