Fail-Safe Control Software

Abstract

The production of “Fail-Safe” software is an elusive goal. And, it is a matter of controversy if such a goal can ever even be reached. Certainly, defects traceable to human error and misunderstanding can never be completely removed. Although, mathematical methods may be used to eliminate some. This chapter argues that barring human errors, and assuming that input and output assertions are true for simple inductively provable subroutines, it should be possible to write fail-safe code for reliable machines provided arithmetic is limited to integer operations.
