T2M Verification IPs UFS VIP


Description and Features

UFS Verification IP validates UFS devices and complies with JESD220E UFS standard. Experts with experience in developing complicated protocols have created the UFS Verification IP. UFS is built on top of our validated Unipro and MPHY Verification IPs to make it more resilient. System Verilog, VMM, RVM, AVM, OVM, UVM, Verilog, System C, VERA, Specman E, and non-standard verification environments all natively support UFS Verification IP. The Smart Visual Protocol Debugger, a GUI-based debugger to speed up debugging, is an optional addition to the UFS Verification IP.
