Abstract
This paper presents a new modeling and simulation technique for CMOS opens. The significance of the method is that both the hazard and charge-sharing effects of all possible opens are modeled in terms of a set of detecting conditions. They are efficiently represented at logic level. Then during fault simulations only these detecting conditions are evaluated to decide if the opens are detected. In this way, all efficient simulation techniques developed at logic level can be applied. The paper shows how the detecting conditions are derived for arbitrary opens. Results of a parallel pattern simulator show a good trade-off of accuracy versus efficiency. >

A technique for logic fault diagnosis of interconnect open defects

TL;DR: The novel features of this work include a diagnostic fault model to capture potential faulty behaviors in the presence of an open defect and diagnosis algorithms that leverage the diagnostic model while circumventing the need for detailed circuit-level (SPICE) simulation and extraction of parasitic capacitance.

Diagnosis of resistive-open and stuck-open defects in digital CMOS ICs

TL;DR: The diagnosis techniques take the test-pattern sequence into account, and therefore, produce precise diagnosis results and the technique handles multiple faults of different fault models.

Fault modeling and logic simulation of CMOS and MOS integrated circuits

A CMOS fault extractor for inductive fault analysis

TL;DR: This analysis shows that the traditional SSA fault model characterizes fewer than half of the faults extracted by FXT; graph-theoretic techniques provide little improvement in the percentage of realistic faults modeled.

Testing oriented analysis of CMOS ICs with opens

TL;DR: It is shown that functional faults caused by opens, i.e. by regions with missing material, cannot be modeled well by a transistor stuck-open, and that the majority of opens which occur in CMOS static circuits manifest themselves as timing faults.
