Verification of SimNML instruction set description using co-simulation

Abstract : The TRACES team at IRIT has developed a description of the RISC-V instruction set in SimNML, which is an Architecture Description Language (ADL). GLISS automatically convert this description into a library supporting, among others, a runnable Instruction Set Simulator. This presentation exposes the validation of our RISC-V description by parallely running and checking the generated simulator with a different source of execution implementing the RISC-V (different simulator or real microprocessor). This work contributes to the confidence we can have into static analysis tools working on program binary representation. In such tools, the instruction set support is a boring and error-prone task whose validity is hard to assert. On the opposite, the SimNML description provides a golden model that is easier to write and that can be tested to detect errors. Once a sufficient level of confidence is obtained about the description, it can be processed automatically to derive properties useful for static analyses work.
