the next generation of domain specific devices. ImperasDV complements the verification tasks for development teams at the forefront of processor exploration. “The flexibility of the RISC-V ISA coupled with the performance of vector extensions is an ideal starting point for AI accelerators for automotive applications,” said Hideki Sugimoto, CTO of NSITEXE, Inc., a group company of DENSO Corporation. “To address the verification requirement for our next generation of processors, we have developed an optimized verification flow with ImperasDV that our design team set up with detailed configuration options to deliver on their comprehensive verification plans that provides the industry leading quality our customers expect.” “The open ISA of RISC-V is enabling a new wave of processor design innovation across the spectrum of compute requirements in almost all market segments,” said Nobuyuki Ueyama, President of eSOL TRINITY Co., Ltd. “High quality processor verification is not a simple task, but the ease of use and configurable approach with RVVI offered by ImperasDV enables the eSOL TRINITY team to support the expert design teams at NSITEXE and other leading adopters of RISC-V in Japan.” “The open standard ISA of RISC-V is enabling a fundamental shift in processor development, with developers able to explore and innovate solutions with optimized solutions for targeted applications,” said Simon Davidmann, CEO at Imperas Software Ltd. “The flexibility of RISC-V on the design side has a direct impact on the verification

the DENSO Corporation that develops and sells high- performance semiconductor IP for automotive applications, has selected ImperasDV™ for advanced RISC-V processor hardware design verification. This expands and extends the use of Imperas simulation technology, models, verification IP and tools by NSITEXE for the next generation of 64bit RISC-V based designs featuring vector accelerators for AI (Artificial Intelligence) automotive applications with verification leading to the level required to achieve ISO 26262 ASIL D. RISC-V is an open standard ISA (Instruction Set Architecture) that allows processor developers to optimize the configuration with both standard extensions and custom instructions. The recently ratified RISC-V Vector Extensions support the compute requirements for hardware accelerators for applications involving linear algebra, which is well suited for the emerging AI algorithms and workloads in advanced automotive applications. ImperasDV is the integrated solution for RISC-V processor verification that provides an adaptable frameworkbasedontheopenstandardRVVI (RISC-V Verification Interface) that supports the core RTL verification with the Imperas reference model in a ‘lock-step-compare’ methodology in addition to test suites and other verification IP. ImperasDV covers the verification tasks for implementations that range from basic controllers through to advanced designs featuring vector extensions, privileged mode security protections, multi-
