PCI Express (PCIe) is an excellent example of where design reuse and adoption has become the norm for design teams. While the verification teams are no longer faced with full compliance testing, they are still challenged with validating that the PCI Express design IP is functioning correctly in the context of the system-on-chip (SoC). This has an effect on the verification effort. The verification teams shouldn’t need to worry about compliance. This white paper gives a few pointers on what should be included in integration test and how to get it done efficiently.
