Abstract(in English) | In this paper, we discuss the application of a seed-selection procedure for LFSR-based BIST to multiple scan chains, combined with a phase shifter. The seed-selection procedure can search the seed of the LFSR that has least test length under the given fault coverage. No hardware overhead is required. By applying this procedure to multiple scan chains, further reduction of testing time can be expected. To avoid linear dependency between scan chains, we combine the procedure with phase shifter. We introduced the procedures for selecting seeds and arrangement of phase shifters under the restriction of limiting additional hardware overheads, and evaluated them in respect to the number of test patterns required to achieve 100% fault coverage. Experimental results shows that that the test length was reduced in comparison with cases in which phase shifters or seed-selection procedures were not applied, under condition where the number of EOR gates in the phase shifter were restricted. |
