As RISC-V processor development matures and the core’s usage in SoCs and microcontrollers grows, engineering teams face new verification challenges related not to the RISC-V core itself but rather to the system based on or around it. Understandably, verification is just as complex and time consuming as it is for, say, an Arm processor-based project.
To date, industry verification efforts have focused on ISA compliance in order to standardize the RISC-V core. Now, the question appears to be, How do we handle verification as the system grows?
