Towards Specification and Testing of RISC-V ISA Compliance⋆

Abstract

Compliance testing for RISC-V is very important. Therefore, an official hand-written compliance test-suite is being actively developed. However, this requires significant manual effort in particular to achieve a high test coverage.In this paper we propose a test-suite specification mechanism in combination with a first set of instruction constraints and coverage requirements for the base RISC-V ISA. In addition, we present an automated method to generate a test-suite that satisfies the specification. Our evaluation demonstrates the effectiveness and potential of our method.
