UFS Verification IP

Overview

UFS Verification IP is compliant with JESD220E UFS specification and verifies UFS devices. UFS Verification IP is developed by experts who have worked on complex protocols before. We have proven Unipro and MPHY Verification IP's and UFS is build on top of it to make it robust.

UFS Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

UFS Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
