Spectrum Software
Industrial Strength Simulation




Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.




Easily Overlooked Features - Winter 2006


This section is designed to highlight one or two features per issue that may be overlooked because they are not made visually obvious with a toolbar button.

Wire Properties Dialog Box
The wires within a schematic can have their properties modified through the Wire Properties dialog box. The Wire Properties dialog box can be invoked by double clicking on a wire when in Select mode. The dialog box will appear as follows:

Wire Properties dialog box

The Wire Properties dialog box contains the following sections:

Node Name(s): Any wire that is connected to a node will automatically have a node number assigned to it. The node numbers are determined by the order that parts are placed in the schematic so they can change as the circuit evolves. For this reason, with nodes of particular interest, it is recommended that node names be assigned to the nodes. One method is to use the Text mode in the schematic and place a text label on a wire directly. The alternative is to enter a name in this field. The node number will always appear in the list but is not available for editing.

Width: The width of the wire can be set with this field. The width can be set anywhere from one to ten pixels. The default width for the wire is one pixel.

Color: The color of the wire can be selected through this button. The default color of the wires is controlled through the Color/Font page of the Circuit Properties dialog box. If a color is set in this field, it will take priority over the color set in the Circuit Properties dialog box.

Change Entire Node: When enabled, any change in either the Width or the Color settings will be applied to all wires that are connected to the node. If disabled, the Width and Color settings will only be applied to the specific wire segment that was selected.
