Digital simulation is the analysis of logic and timing behavior of digital devices over time. PSpice A/D simulates this behavior during transient analysis. When computing the bias point, PSpice considers the digital devices in addition to any analog devices in the circuit. PSpice A/D performs detailed timing analysis subject to the constraints specified for the devices. For example, flip-flops perform setup checks on the incoming clock and data signals. PSpice A/D reports any timing violations or hazards as messages written to the simulation output file and the waveform data file. See Tracking timing violations and hazards on page 632 for information about persistent hazards, and for descriptions of the warning messages. Steps for simulating digital circuits There are six steps in the development and simulation of digital circuits: 1. Drawing the design. For more information on drawing designs see your OrCAD Capture User Guide. Steps 2 through 6 of this process are covered in this chapter. 2. Defining the stimuli. 3. Setting the simulation time. 4. Adjusting the simulation parameters. 5. Starting the simulation. 6. Analyzing the results.
