TLDR
It is shown that all single FET stuck-open faults, in a specific design using a single CMOs complex gate, are detectable by tests that remain valid in the presence of arbitrary circuit delays.
Abstract
In this paper, potential invalidation of stuck-open fault-detecting tests, derived by neglecting circuit delays and charge distribution in CMOS logic circuits, is studied. Several classes of circuits derived from sum of products and product of sums expressions for a given combinational logic function are investigated to determine the testability of FET stuck-open faults by tests which will remain valid in the presence of arbitrary circuit delays. Necessary and sufficient conditions for the existence of tests that will remain valid in the presence of arbitrary circuit delays are derived. Using these conditions, it is shown that all single FET stuck-open faults, in a specific design using a single CMOs complex gate, are detectable by tests that remain valid in the presence of arbitrary circuit delays. For several other realizations, methods to augment them, to insure detectability of all single FET stuck-open faults by tests that will remain valid in the presence of arbitrary circuit delays are proposed. It is observed that in many of the logic circuits investigated it is also possible to avoid test invalidation due to charge distribution.

A cell-replicating approach to minicut-based circuit partitioning

TL;DR: An extension to the Fiduccia and Mattheyses minicut algorithm (1982) allows cells to be replicated in both sides of the partition and can substantially reduce the number of cut nets in a partitioned network below what can be obtained without replication.

Physical Versus Logical Fault Models MOS LSI Circuits: Impact on Their Testability

TL;DR: At the end of an IC production line, integrated circuits are generally submitted to three kinds of tests: 1) parametric tests to check electrical characteristics (voltage, current, power consumption), 2) dynamic tests to Check response times under nominal operating conditions, and 3) functional tests toCheck its logical behavior.
