The error injector tool A comprising counter 10, manually settable count limit circuit 12, control logic 14, delay counter 16, width counter 18 and drivers 20, provides on each of output pair 22, output pair 23, etc., an error pulse which may, if desired, be repeated, and which may be injected into circuitry to be tested in order to test hardware and software error recovery. The output pairs 22, 23, etc., simultaneously pulse, but are at various voltage and current levels suitable for various applications, such as transistor-transistor logic (TTL) and emitter-coupled logic (ECL).
