T2M Verification IPs USB 4.0 VIP


Description and Features

USB 4.0 Verification IP provides a smart way to verify the USB 4.0 component of a SOC or an ASIC. The USB 4.0 Verification IP is fully compliant with standard USB Specification 4.0. The USB 4.0 VIP can be readily customized and optimized for a wide range of specific system applications. USB 4.0 Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env. USB 4.0 Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
