Unknown Blocking Scheme for Low Control Data Volume and High Observability
2007
2007 Design, Automation & Test in Europe Conference & Exhibition
This paper presents a new blocking logic to block unknowns for temporal compactors. The proposed blocking logic can reduce data volume required to control the blocking logic and also increase the number of scan cells that are observed by the temporal compactors. Control patterns, which describe values required at the control signals of the blocking logic, are compressed by LFSR reseeding. In this paper, the blocking logic gates for some groups of scan chains that do not capture unknowns are
