A new methodology is developed in this paper for identifyingpossible path delay faults through at-speed testing of sequentialnon-scan circuits. In the past, different techniques havebeen proposed for diagnosing delay faults in sequential circuitsthrough variable clock control techniques. These techniquesare, however, not readily applicable to commercialhigh-performance ICs. We propose new techniques based oncritical-path tracing which can be used to locate slow pathsin sequential circuits. Strategies have been developed to improvethe diagnostic resolution, which involve deducing internalstate values from the observed circuit outputs and thedetection of fault-free circuit paths. Results of experimentson the ISCAS89 sequential benchmark suite are finally discussed.
