Open Architecture Lightening Talk (1): RISC-V SoC Design Using Open-Source IP, PDK, and EDA | Nobushige Nakajima | Semiconductor Design Department 1, Digital Platform Solution Division, Hitachi Industry & Control Solutions, Ltd. (HiICS)

This presentation introduces our effort to prototype a RISC-V microcontroller using the “chipIgnite” service from chipfoundry, along with open-source RISC-V core IP and design platforms. During the prototyping process, we encountered a number of challenges unique to open-source development—including toolchain preparation, layout design, and verification environment construction. To address these issues, we applied practical approaches such as reusing design assets and clearly defining the applicable scope of open-source tools. This talk shares the insights gained in establishing a design and verification flow through this process and highlights new possibilities for semiconductor development using open-source technologies.
