T2M Verification IPs SDIO UHS-II VIP


Description and Features

A cutting-edge method for confirming SDIO UHS-II implementations is available on the market: SDIO UHS II Verification IP. All command kinds can be generated using it. A robust protocol checker that complies fully with UHS-II Adddendum version 2.00 is the SDIO UHS-II monitor. All protocol tests may be run on the SDIO UHS-II VIP as a test bench, and it also makes it simple to create a large number of patterns and a set of predetermined patterns to stress the DUT. System Verilog, VMM, RVM, AVM, OVM, UVM, Verilog, System C, VERA, Specman E, and non-standard verification environments all natively support SDIO UHS II Verification IP. To expedite debugging, the SDIO UHS II Verification IP offers an optional Smart Visual Protocol Debugger, a GUI-based debugger.
