Verification of an industrial SystemC/TLM model using LOTOS and CADP

Abstract

SystemC/TLM is a widely used standard for system level descriptions of complex architectures. It is particularly useful for fast simulation, thus allowing early development and testing of the targeted software. In general, formal verification of SystemC/TLM relies on the translation of the complete model into a language accepted by a verification tool. In this paper, we present an approach to the validation of a SystemC/TLM description by translation into LOTOS, reusing as much as possible of the original SystemC/TLM C++ code. To this end, we exploit a feature offered by the formal verification toolbox CADP, namely the import of external C code in a LOTOS model. We report on experiments of our approach on the BDisp, a complex graphical processing unit designed by STMicroelectronics.
