SystemC is an IEEE standard system-level language used in hardware/software co-design and has been widely adopted in the industry. This paper describes a formal approach to verifying SystemC codes by providing a mapping to the process algebra mCRL2. The outstanding advantages of mCRL2 are the support for different data types and a powerful tool-set for model reduction and analysis. A tool is implemented to automatically perform the proposed mapping. This translation enabled us to exploit process-algebraic verification techniques to analyze a number of case-studies, including the formal analysis of a single-cycle and a pipelined MIPS processor specified in SystemC.
