Abstract

Executing Formal Specifications with Concurrent Constraint Programming
by
Tim Wahls and Gary T. Leavens, and Albert L. Baker
Abstract
We have implemented a technique for execution of formal, model-based
specifications. The specifications we can execute are written at a
level of abstraction that is close to that used in nonexecutable
specifications.  The specification abstractions supported by our
execution technique include using quantified assertions to to directly
construct post-state values, and indirect definitions of post-state
values (definitions that do not use equality). Our approach is based
on translating specifications to the concurrent constraint programming
language AKL.  While there are, of course, expressible assertions that
are not executable, our technique is amenable to any formal
specification language based on a finite number of intrinsic types and
pre- and postcondition assertions.
