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 - Summer 2003


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.

Clear Cut Wire (CTRL + DELETE)
The common method for deleting multiple objects in a schematic is to drag a select box over the area that is to be deleted. The select box will highlight any components, wires, text, and objects that fall within the drag area. For wires, if even a small portion of the wire segment is within the select box, the entire wire segment will be highlighted. In the figure below, the select box has been drawn to delete the three batteries. Note that for the three wires, the entire wire segment has been selected.

Now if the Clear command is chosen or the Delete key hit, the wire segments will be completely deleted, and only the resistors will be left in the circuit. In some cases, it may not be desirable to have the entire wire deleted. For these instances, the Clear Cut Wire command is available under the Edit menu. This command deletes selected wires by cutting them exactly at the sides of the select box. The CTRL+DELETE hotkey combination may also be used. The figure below shows the result after the Clear Cut Wire command has been invoked. The wire segment outside of the select box has remained in the schematic.
