Together with the Andes certified Imperas reference models, SoC developers can explore the next generation domain-specific solutions.

  • Shubhodeep Roy Choudhury, Managing Director & Co-founder

    Valtrix Systems

    Ideally any test should provide a clear pass or fail indication. In the case of RISC-V processor DV this is achieved with a comparison against a quality reference model.

    STING helps generate portable, architecturally correct and self-checking tests targeted at the corner-case scenarios by automating the comparison of the DUT against the Imperas reference model results.

  • Richard Bohn, Engineering Director

    Seagate Technology

  • Bill McSpadden, Principal VLSI Verification Engineer

    Seagate Technology

    The Imperas Golden RISC-V Reference Model helped us find many bugs in our cores.

    However, the RISC-V architectural tests yielded no bugs, which is expected since the architectural tests are a subset of full verification.

  • Rick O’Connor, President & CEO

    The UVM SystemVerilog testbenches of the OpenHW Verification Task Group, which are publicly available, are well implemented to effectively support multiple RISC-V based 64-bit and 32-bit CPU cores.  The common verification methodology shared by these testbenches does a good job in identifying issues and supporting the analysis and resolution.

    The Imperas reference model incapsulated within the testbenches is a key component to enable the step-and-compare interactive checking approach for efficient error resolution.

  • Rick O’Connor, Founder and CEO

    OpenHW Group

    The OpenHW Group charter is to deliver high quality processor IP cores for our leading commercial members and open source community adoption.

    The lack of electronic design automation (EDA) tools combining model flexibility, and fast and accurate evaluation of performance, power, and reliability is one of the major challenges currently faced by embedded researchers. Even expensive, commercially available tools don't often meet modeling and simulation needs for emerging technologies.The description of processors – i.e., register or gate-level – is rarely available to universities, and commercial licenses are quite expensive. Having free tools with different state-of-the-art processor models allows the exploration of new system architectures.

  • Duncan Graham
