Transient fault tolerance in digital systems

It is hard to shield systems effectively from transient faults (fault avoidance techniques). So some other means must be employed to assure appropriate levels of transient fault tolerance (insensitivity to transient faults). They are based on fault-masking and fault recovery ideas. Having analyzed this problem, the author identifies critical design points and outlines some practical solutions that refer to efficient on-line detectors (detecting errors during the system operation) and error handling procedures. This framework provides a basis for understanding transient fault problems in digital systems. It can be helpful in selecting optimum techniques to mask or eliminate transient fault effects in developed systems
