PCIe Verification IP provides an smart way to verify the PCIe bi-directional bus. The SmartDV's PCIe Verification IP is fully compliant with version 1.0/2.0/2.1/3.0/4.0/5.0/6.0 of the PCIe Specification and provides the following features.
PCI Express Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
PCI Express Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
