ABSTRACT:
Digital circuitry in a data processing system includes parallel signature analysis circuitry having a sampling feature which permits sampling any given signal on all clock phases of the digital circuitry. The parallel signature analysis circuitry provides for selective coupling of a target node to each of the respective inputs of a pair of serially-coupled latches.
