Safeguard Data-Processing System: Debugging a Real-Time Multiprocessor System

Abstract

The debugging of SAFEGUARD software was performed in phases, each with a unique environment, problems, and debugging tools. The unique aspects of each phase are described here with special emphasis on the debugging tools used. Although the multiprocessor configuration introduced new kinds of software "bugs" and complicated the debugging problem, the real-time character of the system had a greater overall impact.
