Abstract

A program and special purpose computer that simulates all of the gates of a computer is used for testing the response of the simulated computer to hardware faults. The computer is simulated normally and tested, and is then simulated with particular hardware faults and tested. The test shows the ability of the computer to operate with hardware faults.

Testing Computer Hardware for Response to Faults by Simulation

A program and special purpose computer that simulates all of the gates of a computer is used for testing the response of the simulated computer to hardware faults. The computer is simulated normally and tested, and is then simulated with particular hardware faults and tested. The test shows the ability of the computer to operate with hardware faults.

The drawing represents a system that provides a generalized simulation of a computer. The specific computer that is to be simulated is defined by parameters that are supplied to the system. The system is also given instructions that are to be executed for the test and data that is to be operated on by the test instructions. The simulating system provides an output that can be analyzed for errors in the design that is represented by the parameters.

As the drawing represents, some of the parameters that define the computer that is being simulated represent faults in the hardware. The test results then show how the computer responds when these faults exist. For example, the computer may be able to tolerate the faults by isolating a defective component and substituting a standby component. Alternatively, the test results may show that a particular fault may affect particular components of the computer and not others.
