Abstract

This paper introduces a Built-In Self Test(BIST) structure referred to as Universal BIST (UBIST).The Test Pattern Generator (TPG) of the proposed UBISTis designed to generate an one of the three classes of testpatterns - deterministic, pseudo-exhaustive, and pseudo-random- to satisf the specific test requirement of a CircuitUnder Test (CUT). Further, while generating the pseudo-randomtest patterns, the TPG can avoid generation of agiven set of patterns declared prohibited for the CUT. Thetheoretical framework of CA noted in [1] has provided thefoundation of this work. Effectiveness of the UBIST structureis validated through extensive experimentation.
