When testing delay faults on critical paths, conventional structural test patterns may be applied in functionally-unreachable states, leading to over-testing or under-testing of t...
It has been shown that the delay of a target path can be composed linearly of other path delays. If the later paths are robustly testable (with known delay values), the target pat...
Due to the development of high speed circuits beyond the 2-GHz mark, the significance of automatic test pattern generation for Path Delay Faults (PDFs) drastically increased in t...
: Conventionally, path delay tests are derived in a delay-independent manner, which causes most faults to be robustly untestable. Many non-robust tests are found but, in practice, ...
Testing of high density SoCs operating at high clock speeds is an important but difficult problem. Many faults, like delay faults, in such sub-micron chips may only appear when th...
