Abstract
A system for testing an error detection circuit includes a fault injection unit for operating the error detection circuit in a fault injection mode. A fault is inserted in either of a primary or a redundant processor. Output signals generated by the primary and redundant processors are compared and checked for a mismatch and the error detection circuit outputs a test signal based on the comparison result.
