Abstract

Testing of the microcode for a processor system which controls devices or adapters must be capable of handling error, sequence and timing considerations correctly. Testing of this code is difficult as all of the conditions with which the code should cope must be set up. A random number generator is incorporated in a program to generate all possible conditions for testing the microcode.
