摘要:
Various aspects of the disclosed technology relate to using capture-per-cycle test points to reduce test application time. A scan-based testing system includes a plurality of regular scan chains and one or more capture-per-cycle scan chains on which scan cells capture and compact test responses at predetermined observation points per shift clock cycle.
