UAS VIP

Description and Features

A SOC or ASIC's UAS component may be intelligently verified with the help of UAS VIP. It offers backwards compatibility with prior UAS requirements. The UAS Verification IP complies exactly with the required UAS Specification. Transferring data between UASs is possible at full speed (12 Mbit/s). The UAS VIP comes with a comprehensive test suite that covers the majority of potential scenarios. It executes all conceivable protocol tests in a guided or highly randomized manner, adding the potential to build a large range of situations to successfully validate the DUT. In this manner, the whole protocol violation is detected. SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E, and non-standard verification environments all natively support UAS VIP.
