MIPS selects Imperas Reference Models for RISC-V Processor Verification

Oxford, United Kingdom, November 29th, 2021Imperas Software Ltd., the leader in RISC-V simulation solutions, today announced with MIPS, Inc., the processor technology company focused on the commercialization of RISC-based processor architectures and IP cores, the continuation and extension to the long-standing relationship with simulation and verification support for RISC-V. Since 2010, MIPS has partnered with Imperas for proprietary simulation technology and reference models for both internal engineering and customer ISS solutions. As the design and verification team transitions to the RISC-V open ISA (Instruction Set Architecture), the Imperas reference models for RISC-V form the essential reference for the processor functional verification tasks.

The latest RISC-V verification ‘step-and-compare’ methodology can be used to verify an RTL processor implementation against the Imperas golden reference model encapsulated within a SystemVerilog environment. This covers asynchronous events and offers a seamless, time-saving transition to debug analysis when an issue is found. More details on test benches with Imperas RISC V verification reference models are available at www.imperas.com/riscv.

Since the main role of a central processor is to execute software, software plays a major role in the complete design cycle from the initial project concept to the detailed functional verification, and in the case of processor IP, beyond into the final SoC design and end application development. SoC developers select processor IP based on many factors, however, one of the key deliverables that supports the ease of use is a high-quality ISS to support software development. Since 2010, the MIPS core IP deliverables have included the Imperas based ISS, and as a consequence Imperas technology has helped to support many projects in applications such high-performance wireless communications, networking, automotive and AI applications, with major customers including MediaTek and Intel Mobileye.

“As the MIPS design and verification teams transition to RISC-V, we see a lot of benefits from adopting the open ISA specification,” said Don Smith, Director of Engineering at MIPS, Inc. “As an IP company, we have a significant focus on the quality and verification of our processor IP deliverables. Imperas are the leaders in RISC-V simulation and verification and, with more than a decade of collaboration, they are the obvious DV partner for MIPS and its new RISC-V offerings.”
