Digital Logic Simulation in a Time-Based, Table-Driven Environment

Digital simulation is the process of modeling, by computer programs, the behavior of a digital network. Digital fault simulation is the modeling of a digital network in the presence of a physical defect. The term "fault" is used to refer to some representation of a physical defect. A simple example of this is the case where an input connection to an AND gate is broken. This would be referred to as a stuck-at-1 fault. Hence the phrase fault simulation.
