Digital Simulation

B2 Spice v4 also includes an interactive pure Digital Mode, which offers special features unavailable in the Mixed Mode environment.

With B2 Spice A/D v4, set up intricate digital circuits and run a fully interactive simulation.  Use  input ports, clocks, bidirectional ports, toggle switches, keypad and other instruments to feed data into your circuit as the simulation runs and see the results immediately. 

With B2 Spice A/D v4, you can start and stop at will.  You can also run the simulation at slow or fast progression or even single step through time intervals to see what is happening with your circuit.

Wires can be color coded by strength so you can tell at a glance what's happening between devices.  Use the probe tool to view the state and strengths of pins or wires or anywhere in between.

B2 Spice A/D v4 also allows you to make new parts from an existing circuit. You can then use your custom part as a new part in a new circuit. Plus, once you use your new part in a different circuit and while running a simulation, you can open up the original circuit and probe inside the subcircuit to see what is happening.

When you want to see the overall picture, switch to the highly customizable Digital Timing diagram to see a trace of each input and output signal.

You can select which signals to display, the size of the graph interval, color of each signal, and size and color of any font.
