Abstract:

This paper describes a low power programmable generator capable of producing pseudorandom test patterns with desired toggling levels and enhanced fault coverage gradient compared to best-to-date BIST-based PRPGs. We introduce a method to automatically select several controls of the generator allowing easy and precise tuning. The same technique is subsequently employed to deterministically guide the generator toward test sequences with improved fault-coverage-to-pattern-count ratios. Experimental results obtained for industrial designs illustrate feasibility of the proposed test scheme and are reported herein.
