Abstract

A method is disclosed that uses electrically erasable programmable read-only memories (eeproms) to broaden automated test coverage. Automated testing has long been used to increase the efficiency of testing hardware. Today, automated testing is being employed in the testing of software. For example, power can be automatically applied and removed repeatedly. This will cause a system to go through its boot sequence repeatedly and the results can be recorded for future analysis. Additionally, electronic signals can be applied automatically and results noted. System software tests may require changes in hardware configuration to test all software paths. But, making configuration changes is frequently a labor intensive task usually resulting in less paths and configurations being tested. What is needed is an automatic method for changing hardware status and configuration and providing simulated conditions and artificial stimuli. Many computer systems contain eeproms that contain data including such information as part number, serial number, version levels, mappings, etc. and the software being tested obviously has access to these eeproms.
