Abstract
A low power scan architecture is formed of a conventional scan architecture. The conventional scan path is divided into equal parts and each part is operated in sequence. An adaptor receives the conventional shift and capture control siqnals from a conventional tester and provides separate shift and capture control siqnals for each of the scan path parts. The adaptor also receives additional select control siqnals from the tester for selecting operation of individual ones of the scan path parts. The disclosed architecture reduces power consumption during testing by a fraction representing the number of equal parts, while maintaining the same test time.
