Mix Analog and Digital Signals

Combine analog circuit behaviors with digital models to create more detailed representations of electronic systems

In electronic systems that combine analog processing with logic gates, several parameters are essential to the overall behavior of the system. These parameters include the finite slew rate of circuit output signals, the propagation delay of signals, and the exact decision threshold of circuit inputs. Add blocks to your model to include these effects in time domain simulations of the system.
