Abstract

This article describes a technique which provides the capability for the same maintenance assurance tests (MATs) to be executed in stand alone as well as in a multi-tasking environment. Traditionally, diagnostic programs which operate in a stand-alone environment cannot be run in a multi-tasking environment (concurrent diagnostic environment). Therefore, two sets of diagnostic programs for the same hardware must be written based on the operating environment. This leads to multiple development of the same function. Also, without concurrent diagnostics, the entire system must be taken down in order to diagnose one failing component. In the technique disclosed herein a diagnostic control program is used to shield the diagnostic routines basic assurance test (BAT) and MAT from knowing its operating environment.
