Chapter 19. Mixed Simulation
PSpice uses the same simulation engine for analog and digital circuits. The simulation results in Probe share the same time axis but are split into separate analog and digital plot windows. Analog and digital components in a circuit are connected together at nodes. In PSpice there are three types of connecting nodes: analog, where all connected parts are analog; digital, where all connected parts are digital; and interface, where there is a mixture of analog and digital parts. Interface nodes are automatically separated into one analog node and one or more digital nodes by inserting analog and digital interface subcircuits, which are either analog to digital ...
