It is shown that in most cases modulo weight-based codes can achieve high fault detection capabilities of around 99% with just three check bits and without constraining the circuit structure. Modulo weight-based codes present a way of exploiting the circuit structure to increase fault detection capability. An optimum choice of weights for the code can be made using information about the circuit structure. The paper presents an efficient algorithm to achieve the weight assignment based on simple estimates of the probabilities of the existence of sensitized paths from the signal line to the circuit outputs. Finally, a self-checking checker design is presented for the proposed module weight-based codes.","PeriodicalId":334770,"journal":{"name":"Proceedings 6th IEEE International On-Line Testing Workshop (Cat.

Non-intrusive concurrent scan monitoring is an easy-to-implement vector-based testing procedure, handicapped by two main factors: the interval for operating vectors to match test patterns and test data to be stored. The paper presents an evolution of this testing technique. Besides decreasing the average latency interval up to three orders of magnitude, it also reduces the memory required for test-data and improves the on-line fault-coverage.","PeriodicalId":334770,"journal":{"name":"Proceedings 6th IEEE International On-Line Testing Workshop (Cat.
