This analysis determines the dc operating point of the circuit with inductors shorted and capacitors opened.

A dc analysis is automatically performed prior to a transient analysis to determine the transient initial conditions, and prior to an AC small-signal, Noise, and Pole-Zero analysis to determine the linearized, small-signal models for non-linear devices.


Enter a brief description of the type of analysis. The text entered is the title of the document in which the simulation results will be stored.


Specify the temperature at which the simulation will be performed.

Analysis Mode

Specify whether a single or multiple analysis should be performed. The multiple analysis performs several consecutive simulations, varying the value of some parameters at each step. When a multiple analysis is selected, the Setup button is activated. Click on the button to activate the dialog in which to set the specific parameters for the selected analysis mode.

The following analysis modes are supported, click a link to learn more about that analysis mode:

Collect Data For

Specifying the simulation data to be collected. Simulations, especially multiple simulations, can produce a large amount of data, causing excessive memory usage and lower simulation speed. This section allows you to specify which information resulting from the simulation should be stored. Select one of the following options:


Click on this button to activate the dialog box in which to set the options of the simulator. The options set are only valid for the current analysis and replace those defined in the general tab of the simulator options.


Click on this button to activate the dialog box in which to set the diagrams and the list of vectors to be included in the diagrams. See the Plot dialog box. The diagrams will only be created if a multiple analysis mode has been selected.
