# Automatic datapath abstraction in hardware systems

## Abstract

- 1.
For a subclass of “control-intensive” ICS models, we prove that finite small instantiations can be used to decide the properties without sacrificing accuracy. A linear time algorithm for recognizing these subsets is given. These results also hold for the standard finite-state systems and thus also provide some generic methods for automatic data abstraction for such systems. Using these results, we are able to verify a memory model by reducing integer data values to binary, and unbounded memory addresses to a small number.

- 2.
For verifying properties of circuits with complex datapaths, the model can be executed symbolically to find the reachable states. In some cases, the set of reachable states is finite, and the verification can be completed exactly. In other cases, given

*n*, the verifier checks that no errors of length less than*n*exist.
