Overview

Imperas RISC-V Processor Verification IP (VIP) is a commercial verification solution provided by Imperas Software Ltd that targets RISC-V processor implementation verification. The VIP combines a golden reference model of the RISC-V ISA with architectural validation test suites, directed-test generation capabilities, and built-in functional coverage monitors. Together these components enable design teams to verify RTL processor implementations against the ratified and near-ratified RISC-V specifications using a step-and-compare methodology.
