Questa Verification IP for PCIe supports all PCIe speeds from Gen 1 to Gen 6 to provide a complete verification solution for designs containing PCIe interfaces. Built upon native System Verilog and UVM, QVIP for PCIe provides bus functional model (BFM) with complete functionality on latest specification for all PCIe use models. QVIP for PCIe comes with support for all kinds of packets/stimulus over a PCIe interface, ensuring extensive coverage of verification scenarios and exhaustive checking with built in assertion checks. Architected for ease-of-use, QVIP is easy to integrate in all test benches in minimal time, enabling rapid and productive verification. QVIP is integrated with all Siemens EDA functional verification tools and enables verification on all platforms, ensuring fast and complete verification closure. The QVIP supports on all major simulators (Questa Sim, VCS, and Incisive) and methodologies (UVM). QVIP for PCIe enables verification of PCIe interfaces in various configurations for verification RC, EP, and Switches over PIPE and Serial interfaces.
