Refining specifications to programmable logic.
Electronic Notes in Theoretical Computer Science, 70(3) pp. 385–395.
Combined hardware/software systems are increasingly being used for safety-critical systems, with hardware taking processing load off the software. To attain the necessary safety integrity levels, new safety standards require that the correctness arguments for safety-critical hardware and software are developed together with the same rigour as for software alone.
In this paper we describe work in progress on the continuing development of such a notation and proof system. Based on process description using Synchronous Receptive Proof Theory, we propose refinement rules for developing a specification into an SRPT implementation.
