Abstract
A circuit includes a scan chain comprising a cell structure, wherein the cell structure comprises a first plural number (N) of stages, and each of the stages is configured to store a bit. The circuit includes a second plural number (S) of multiplexers operatively coupled to the scan chain, wherein the S is determined as where the M represents a diagnostic resolution. The multiplexers are each configured to receive a respective one of S control signals to selectively bypass a corresponding subset of the stages.
