Analysis Modes

There are various analysis modes available in the MPLAB® Mindi™ Analog Simulator. The majority of the analysis settings can be set and changed by going toSimulator > Choose Analysis or by clickingF8.

Simulator Command Window

The MPLAB Mindi Analog Simulator environment has a Simulator Command window feature that allows you to update or change simulator settings by manually entering commands as texts. To open the Simulator Command window, create a new schematic or select an existing schematic, clickF11. If you clickF11 a second time, the command window will be hidden.

The Simulator Command window and the Choose Analysis box settings are synchronized with each other. After you make a simulation setting change in theChoose Analysis box, the texts in the command window are updated.

Starting a Simulation

To start a simulation in Normal (i.e., Synchronous) mode, clickSimulator > Run Schematic, clickF9 or clickRun in theChoose Analysis box.

In Synchronous Simulation mode, while the simulation is running, you cannot perform any MPLAB Mindi Analog Simulator functions. In Asynchronous Simulation mode, the simulation runs in the background and you can perform other tasks simultaneously, e.g. creating or changing a schematic.

Pausing a Simulation

To pause the simulation, clickPause in theSimulator - Running box.

To restart the simulation, clickResume orSimulator > Resume. When a simulation is paused, you can perform other tasks including plotting simulation results. This gives you a real-time view of the simulation.

If you decide not to continue after pausing, you don't need to explicitly abort; you can simply start a new simulation run. You will be asked if you would like to resume the pending run. If you clickNo, the pending run will be aborted and a new run will start automatically.

Aborting a Simulation

ClickSimulator > Abort. When you abort a simulation, you will not be able to resume this run.

SIMPLIS is a circuit simulator specifically designed to handle the simulation challenges of switching power systems. Like SPICE, SIMPLIS works at the component level but typically can perform a transient analysis of a switching circuit 10 to 50 times faster than SPICE. For switching power systems, the Piecewise Linear (PWL) modeling and simulation techniques employed by SIMPLIS result in qualitatively superior convergence behavior compared to SPICE.

SIMetrix is a general analog and mixed-signal simulator. It includes an enhanced SPICE simulator, schematic editor, and waveform viewer in a unified environment. It is easy to use, offers good accuracy and performance, and rapid convergence for a broad range of analog and mixed-signal design applications.
