ABSTRACT:
Apparatus is disclosed for forming scan data path subchains from the elemental memory units of a digital system, and interconnecting the scan data path subchains to form an extended serial shift register for scan testing. The method and apparatus for forming the interconnections ensures that data is passed from one subchain to another without data being lost due to clocking irregularities.
