| Summary: | Demand for scalable hardware verification is ever increasing. We propose an unbounded safety verification framework for hardware, at the heart of which is a software verifier. To this end, we synthesize Verilog at register transfer level into a software-netlist, represented as a word-level ANSI-C program. The proposed tool flow allows us to leverage the precision and scalability of state-of-the-art software verification techniques. In particular, we evaluate unbounded proof techniques, such as predicate abstraction, k-induction, interpolation, and IC3/PDR; and we compare the performance of verification tools from the hardware and software domains that use these techniques. To the best of our knowledge, this is the first attempt to perform unbounded verification of hardware using software analyzers.
