SiFive’s Core Designer allows our customers to customize our broad portfolio of RISC-V Core IP for their particular application. The donation of a robust, commercial-quality simulator such as riscvOVPsim™ will enable them to adopt RISC-V even faster. This is the level of close industry collaboration that will drive the successful adoption of RISC-V.

Yunsup Lee, co-founder and CTO


The work of the RISC-V Compliance Task Group is vital to the success of RISC-V and anyone trying to design or sell RISC-V based products. We welcome the contributions of Imperas and believe that using riscvOVPsim as one of the reference simulators could be highly valuable in the overall compliance effort.

The RISC-V ISA Formal Spec Task Group will produce a Formal Specification for the RISC-V ISA. We see the introduction of riscvOVPsim as an excellent reference platform to test and verify with.

RISC-V momentum and interest is wide-ranging across academic and industry. In providing support for the IIT Madras Shakti processors, InCore sees an increasing attention to test and verification that will be supported with riscvOVPsim.

G. S. Madhusudan, CEO


RISC-V has made the successful transition from an academic project to achieve commercial adoption. We see a universal need for quality and design assurance that can be supported by riscvOVPsim across all projects as PULP RI5CY cores are increasingly implemented in commercial SoC development.

As one of the first IP providers for RISC-V cores, we see the importance of compliance as the RISC-V ecosystem develops. riscvOVPsim is a solid starting point for developers looking for a RISC V ISS (Instruction Set Simulator) for test and verification.

Alexander Redkin, CEO


As RISC-V adoption grows throughout the industry in a variety of application areas, so does the need for robust simulation support from both commercial and open source suppliers. We welcome Imperas' contributions to the rapidly accelerating RISC-V ecosystem.

Karel Masarik, CEO and Co-Founder

Codasip Ltd

In commercial semiconductor IP, quality is perhaps the highest priority for successful customer engagements, the extensive test and verification process is best achieved with extensive simulator-based testing. We have already certified the Imperas RISC-V model and simulation technology for Andes N25 and NX25 processors so expect that riscvOVPsim will quickly be adopted as an industry standard reference simulator.

Charlie Hong-Men Su, CTO and Senior Vice President

Andes Technology Corp

The free and open nature of the RISC-V ISA fosters unprecedented levels of processor innovation. To harness this design freedom, the ecosystem requires robust development tools and the assurance that verification test benches can be developed and validated on supplier-neutral platforms. Imperas’ new riscvOVPsim is an important suite of tools that addresses this challenge.

Rick O’Connor, Executive Director

RISC-V Foundation

Imperas virtual platform solutions and open-source models help accelerate embedded software development, debug and test for our customers. This certification demonstrates our great confidence in the accuracy and value of Imperas support for V5 AndesCore N25 and NX25 processors reference models and simulators for use by our customers, partners, and ecosystem
