Abstract: In recent times, there is an increased adoption of RISC-V based implementations amongst Product R&D or R&D Service Organizations. These RISC-V cores are either developed within the organization or customized using the available open source RISC-V cores targeting their specific applications.
In order to verify these highly configurable RISC-V based SoCs, there is a need to make the verification environment also configurable to achieve rapid verification quality before tapeout. To aid this end goal, we propose an automated generation of the verification test bench modules and the SoC verification environment. This makes the environment more robust by avoiding human errors during test bench development thus improving productivity. The talk will cover the following topics adopted as a standard approach of verifying a readily available open source RISC-V based SoC and the steps to achieve value addition during the verification process.3 Key Points:
  • Bridge/Interconnect customized block features can be verified using automated generation of reusable, parameterized UVM VIPs
  • Automated build of test bench environment, top file creation, hierarchical signal connection files etc
  • Reducing SoC integration time and avoiding manual errors by automating the required test bench files and re-using block level verification components
