Considering the modularity of RISC-V, proving the compatibility of implementations against the ISA has become critical to prevent fragmentation and ensure its success. The test suite needed to achieve this should cater to all legal enumerations of the ISA and determine with high confidence, the ISA compatibility of the target. This paper proposes open-source tools(RISCV-ISAC and RISCV- CTG) which significantly automate building and maintenance of a high quality and scalable test suite. RISCV-ISAC collects coverage from execution logs and checks for data propagation to signature. RISCV-CTG is a coverage driven test generator, which generates minimal tests for maximum coverage with RISCV-ISAC.
