Abstract

The paper introduces a new algorithm for the automatedsynthesis of phase shifters - circuits used to remove effectsof structural dependencies featured by two-dimensionaltest generators. The algorithms presented in the papersynthesize in a time-efficient manner very large and fastphase shifters for built-in self-test environment, with guaranteedminimal phaseshifts between scan chains, and verylow delay and area of virtually one 2-way XOR gate perchannel.
