Symbolic Simulation of SystemC AMS Without Yet Another Compiler

Abstract

Modeling languages first of all support simulation that is considered as reference by designers. Formal verification and synthesis share the same languages. However, they usually require a separate, dedicated compiler. As modeling languages such as SystemC have reached a high complexity, it is very hard to support reasonably large language subsets, and to guarantee consistency with simulation semantics. This paper shows a way to use the simulator itself to generate a formal model of the complete dynamic behavior. Compared with using yet another compiler, this permits to improve consistency with simulation semantics, and to combine simulation with other use-cases. We concretely focus on symbolic simulation of SystemC AMS ([1], [2], IEEE Std 1666.1-2016), for which we generate AADD and BDD for symbolic simulation.
