Abstract
We present a methodology in which the behavior of a switch level device is specified using abstract parameterized regular expressions. These specifications are used to generate a finite automaton representing an abstraction of the behavior of a block of memory comprised of a set of such switch level devices. The automaton, in conjunction with an Efficient Memory Model [1], [2] for the devices, forms a symbolic simulation model representing an abstraction of the array core embedded in a larger design under analysis. Using Symbolic Trajectory Evaluation, we check the equivalence between a register transfer level description and a schematic description augmented with abstract specifications for one of the custom memories embedded in the MPC7450 PowerPC processor.KeywordsPartial OrderRegular ExpressionComplete LatticeInput StringInput SymbolThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
