Abstract
A system is dataindependent with respect to a data type X iff the operations it can perform on values of type X are restricted to just equality testing. The system may also store, input and output values of type X. We study model checking of systems which are dataindependent with respect to two distinct type variables X and Y, and may in addition use arrays with indices from X and values from Y. Our main interest is the following parameterised modelchecking problem: whether a given program satisfies a given temporallogic formula for all nonempty finite instances of X and Y. Initially, we consider instead the abstraction where X and Y are infinite and where partial functions with finite domains are used to model arrays. Using a translation to dataindependent systems without arrays, we show that the mucalculus modelchecking problem is decidable for these systems. From this result, we can deduce properties of all systems with finite instances of X and Y. We show that there is a procedure for the above parameterised modelchecking problem of the universal fragment of the mucalculus, such that it always terminates but may give false negatives. We also deduce that the parameterised modelchecking problem of the universal disjunctionfree fragment of the mucalculus is decidable. Practical motivations for model checking dataindependent systems with arrays include verification of memory and cache systems, where X is the type of memory addresses, and Y the type of storable values. As an example we verify a faulttolerant memory interface over a set of unreliable memories.
