Abstract :
Arithmetic-function modules, which are available in many circuits, can be utilized to generate test patterns and compact test responses. An accumulator-based scheme along with a procedure to find maximum-length nonlinear sequences for bit-serial test-pattern generators is proposed. The proposed scheme achieves good fault coverage with low hardware overhead and short test sequences
