Consider a combinational circuit C, synthesized as a network of modules with a single output (library complex gates or arbitrary sub-circuits) with a set of primary outputs OUT, a set of primary inputs IN, and a set of internal nodes INT.
A similar pattern-related fault modelling approach, called functional fault model, was proposed earlier in  for the module-level fault diagnosis in combinational circuits based on solving systems of Boolean differential equations.
Let [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] be p lines in a combinational circuit C implementing scalar function f, and let note with [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] local functions of these p lines.
Similar conditions holds for bridging fault, inducing wired-OR, between p internal lines in combinational circuit C:
We also proved by constructing combinational circuit with the same QCA circuit as comparotr and parity generator.
We also developed fixed QCA circuit which can be used to get all Boolean logic functions and also to build combinational circuits such as comparators, parity generators and checkers.
A combinational circuit based on this minimal form offers the shortest response time, but not at all the smallest size.
In this paper, we described an evolutionary technique to engineer compact, efficient and creative digital combinational circuit given the expected input/output behaviour.
With Agilent, TTA is able to broaden its scope of services while adding efficiencies found in the Agilent 3070 family of in-circuit and combinational circuit
board test systems, TTA will add new board test resources from Agilent that provide transportable and repeatable test results.
In this work is presented new multilevel multi-resource partitioning algorithm for partitioning large combinational circuits
in order to efficiently use existing and commercially available FPGAs packages.
After describing Simulink and Stateflow, he discusses Simulink model building for fault modeling and simulation for combinational circuits
and sequential circuits.
In this paper is used simulation-based approach for 15 combinational circuits
of the MCNC benchmark.
