Abstract :
An implementation of a low-cost, time-extended invariant-based concurrent test scheme for linear digital systems is presented. Both feedback and non-feedback systems are analyzed to identify gate and RT level implementation requirements for high on-line fault coverage. Simulation results on implementations satisfying the outlined requirements indicate that low latency, 100% on-line fault coverage is attained within hardware costs comparable to those of scan insertion
