This work presents a technique to correctly deal with non-stuck-at faults in FCMOS circuits making use of complex macrogates. This method can be applied to any gate-level fault simulator providing, for each line of the circuit, the observability status that is directly related to that of individual devices in the actual macrogate implementation. Conductance conflicts are correctly solved to detect bridgings and transistors stuck-on. Fault coverage results are presented and discussed for two typical FCMOS circuits. Results obtained on all ISCAS benchmarks show that the time required for the fault simulation of CMOS faults is comparable to that of stuck-ats. © 1991 Kluwer Academic Publishers.

Abstract
This work presents a technique to correctly deal with non-stuck-at faults in FCMOS circuits making use of complex macrogates. This method can be applied to any gate-level fault simulator providing, for each line of the circuit, the observability status that is directly related to that of individual devices in the actual macrogate implementation. Conductance conflicts are correctly solved to detect bridgings and transistors stuck-on. Fault coverage results are presented and discussed for two typical FCMOS circuits. Results obtained on all ISCAS benchmarks show that the time required for the fault simulation of CMOS faults is comparable to that of stuck-ats. © 1991 Kluwer Academic Publishers.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
