RISC-V offers many different permutations of base instructions, standard optional extensions and custom instructions – that raises concerns about implementations and the risk of fragmentation.
Codasip’s internal testing already uses an internal instruction-accurate model, several sources of direct and random testing (internal and externally provided), and several different technologies to check and ensure processor compliance.
Imperas configurable reference models are tested and enable all the configuration options needed to support this comprehensive view.
Codasip set up the infrastructure and test frameworks around the Imperas RISC-V Reference Models to test all configurations with the ability to adapt for new roadmap features.
