Our simulator, PSIM, allows you to randomize the contents of the register
space any time during program execution. This feature was put in to ferret
out this exact problem.

Your idea is excellent! There would need to be a lot of information about
what registers this rule should apply to as some non-ram registers, such
as RTCC on the PIC, would not qualify for this treatment.
