A cost-effective built-in self testing (BIST) method for the detection of delay faults is presented. A multiple-input signature register (MISR) with a constant parallel input vector is used as a test pattern generator. To reduce the test length of the MISR, a two-step approach is proposed. First, deterministic delay test generation is employed to determine a set of two-pattern tests which detect all testable path delay faults. Second, a minimal number of constant MISR input vectors is calculated such that the state sequences generated by the MISR include the pre-determined test set. The second step is formulated as a set covering problem. As the number of MISR input vectors may be exponential in the number of stages of the MISR, their calculation and the set covering are performed implicitly with BDDs. Experimental results reveal that in almost all considered cases a maximum robust path delay fault coverage is obtained with less than 100 MISR input vectors.
