ABSTRACT:
The testing system is provided with a diagnostic processing apparatus which is independent from a computer to be tested. The diagnostic processing apparatus operates based on a clock signal which is separate from another clock signal used in the computer to asynchronously issue a fault generation command to the computer. The computer is provided with a register for storing particular fault mode information. The computer is responsive to the issued fault generation command for enabling the stored fault mode information so as to generate an asynchronous pseudo-fault in the computer for testing purpose.
