Introduction to RISC-V Processor Verification Methodology – Larry Lapides​VP Sales, Imperas Software


For SoC designers adopting RISC-V, tackling the processor DV tasks presents some new challenges. The established SoC flows have some standard assumptions – test benches written for UVM SystemVerilog flows and known good processor IP from a mainstream supplier. The availability of open-source RISC-V cores and the growing interest to add custom extensions are all increasing the DV tasks.

The basic RISC-V compliance suite is insufficient to achieve the coverage requirements for a complete DV test plan, and comparison-based testing with predicted results has built-in limitations. The latest work on dynamic test benches allows the processor RTL to be subjected to the full range of asynchronous events and debug operations. Interactive dynamic test benches allow both detection of issues and also efficient investigation for a timely resolution. This talk will present the latest results from extensively testing some popular open-source cores, including discussion of a new open standard for test bench interfaces.


Prior to joining Imperas, Larry ran sales at Averant and Calypto Design Systems. He was vice president of worldwide sales during the run-up to Verisity’s IPO (the top performing IPO of 2001), and afterwards as Verisity solidified its position as the fifth largest EDA company. Before Verisity and SureFire (acquired by Verisity), Larry held positions in sales and marketing for Exemplar Logic and Mentor Graphics. Larry was recently an Entrepreneur-in-Residence at Clark University’s Graduate School of Management, where he developed and taught a course on Entrepreneurial Communication and Influence. Larry holds an MBA from Clark University in addition to his MS Applied & Engineering Physics from Cornell University and BA Physics from the University of California Berkeley.
