Abstract: A verification environment enables verification of runtime switch-over—i.e., a switch-over without restarting the device under test—between multiple I/O protocols that share a same physical interface. The device under test can be a switch unit having multiple logical protocol processing units and a logical protocol multiplexor. The verification environment includes a switch-over detector which monitors the state of the device under test, and a switch-over controller that controls the switch-over sequence by pausing and re-starting traffic on all or specific protocol drivers of the verification environment.

Abstract: A method and apparatus that allow packet based communication transactions between devices over an interconnect bus to be captured to measure performance. Performance metrics may be determined by capturing events at various locations as they pass through the system. Performance may be verified at run time by computing performance metrics for captured events and comparing such metrics to predefined performance ranges and/or self learned performance ranges. Furthermore, embodiments of the present invention provide for dynamic tailoring of bus traffic to generate potential failing conditions. For some embodiments, performance verification as described herein may be performed in a simulation environment.
