An algorithm to reduce test application time in full scan designs

An algorithm for generating a test with fewer test clocks for full scan designs by using combinational and sequential test generation algorithms adaptively is presented. Heuristics combining tests measures and scan strategies are introduced. The algorithm, 'Test Application time Reduction for Full scan designs' (TARF), is implemented and tested on a set of ISCAS sequential benchmark circuits. The results show that TARF achieves the same test coverage as combinational test generators but with fewer test clocks.<
