Abstract :
We propose an autonomous, deterministic scan-BIST architecture that allows compact, precomputed test sets with complete fault coverage to be used for field testing. The use of such short test sequences is desirable in safety-critical systems since it reduces the error latency. It also reduces testing time and therefore allows periodic field testing to be carried out with low system downtime. We synthesize the BIST logic for several ISCAS 89 benchmarks and industrial circuit modules and show that the BIST overhead is low in all cases. The proposed design can also be efficiently used with a mixed-mode BIST strategy
