You don't say what language your programme's written in...there are some
labguages that can be shown to have "normal forms", analoguous to the
normal forms of Boolean expressions. This allows programmme modifications
to be checked. occam2 is such a language (with a few restrictions, I
believe), and reputably a semi-automatical checker was used for
transformations of a behavioural FPU description.
