Abstract :
A new BIST structure, based on the information provided by the XY-operation (Lissajous curves) is introduced in this paper. A digital signature is obtained which is used to discriminate catastrophic as well as parametric defects. High fault coverage is achieved when applying the proposed BIST on an ITC´97 benchmark circuit where 92% of the catastrophic defects and 87.5% of the parametric defects analyzed produced digital signatures clearly distinguishable from the golden signature
