PSEUDO FAULT TESTING SYSTEM

摘要

PURPOSE:To reduce man-hour for certification by providing a pseudo fault test system which can set the address of a micro-program (muP) in an information processor at the desired timing of generating a pseudo fault without being affected by the change of the muP. CONSTITUTION:A pseudo fault trigger address table 23 registering a trigger muP address group is provided in the muP 22 of a processor 2 for pseudo fault generation, and a pseudo fault trigger parameter table 12 registering a parameter group fro calculating a trigger muP address corresponding to the test timing from the table is provided in a processor 2 for pseudo fault certification. A pseudo fault injection program 11 calculates the trigger muP address from the trigger address table 23 by using the parameter for test in the parameter table 12 and injects the fault by using this address.
