Abstract

Scan architectures are commonly used to testdigital circuitry in integrated circuits. This paperdescribes a method of adapting conventional scanarchitectures such that they operate in a low powermode during test. The adapted scan architecturesmaintain the test times of the pre-adapted scanarchitectures. Also, the adaptation occurs in a manner that enables the test patterns of the preadapted scan architecture to be directly reusable in the adapted scan architecture.
