UAS VIP

Overview

UAS VIP provides an smart way to verify the UAS component of a SOC or a ASIC. It provides backward compatibility support for earliers versions UAS specifications. The SmartDV's UAS Verification IP is fully compliant with standard UAS Specification.

UAS data transfer can be done at full speed(12 Mbit/s). The UAS VIP includes an extensive test suite covering most of the possible scenarios. It performs all possible protocol tests in a directed or a highly randomized fashion which adds the possibility to create most wide range of scenarios to verify the DUT effectively. This way it detects the violation of protocol completely.

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

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