B2 Spice V5.0 Simulation Mode

B2 Spice v5 has two modes for analyzing a circuit, an non-interactive Test (see below) mode with defined parameter for each Test, and a interactive Simulation, which runs indefinitely until reset by the user.

The Simulation mode is controlled by the main toolbar and consists of the Reset, Pause, Step, Walk, and Run buttons. These control the progress of operation of the Simulation. The Step Ceiling and Update Interval settings control how the Simulation progresses and how often the results are updated.

In the Sweep tab, click Set up Sweeps to enter the dialog to set up your sweep parameters. This will bring up the following dialog box (the data will depend on what you have in your circuit):

Unlike Tests, the only thing required to run a Simulation is that you press the green Run button to start the simulation. Once the simulation is running, the simulation can be paused by clicking on the Pause button. Resume the simulation by again pressing the Run button.
The Step button increments the simulation time by one step and pauses. Each subsequent click of the Step button increments the simulation by another step.

The Walk button starts the simulation but increases the simulation by the walk factor.

The Simulation runs a continuous Transient simulation on the circuit starting at time zero and incrementing by the Step Ceiling setting. Results of the Simulation are displayed in either the schematic with the Circuit Visualization or any of the Virtual Instruments. The results are refreshed by the time specified in the Update Interval setting.

Tests are located in the Toolbox window and represent the traditional analyses found in SPICE. Unlike the Simulation mode, Tests must be set up and run through a set range

In addition to a single test, each test can also be swept over a range of available parameters from the circuit and its devices. This means that, for instance, you can now step a resistor's value in any of the 12 tests. Parameter Sweeping.

Like the swept tests, a Monte Carlo analysis can be performed on each test.
