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


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

Navigating Schematics
There are multiple methods for navigating schematics. The best method to use depends both on the individual user and the size of the schematic. The first two methods are common to any Windows user.

Schematic scrolling
Scroll the schematic using the vertical or horizontal scroll bars. This is the conventional method.

Use the Zoom-Out or Zoom-In commands to be able to resize the schematic with a different zoom scale to get your bearing.

The next few methods are often easier to use but not as obvious as the first two.

Pan the schematic. Panning means to move the view to a different part of the schematic. In keyboard panning, you use CTRL+<CURSOR KEY> to move the view in the direction of the cursor key arrow. This movement is similar to using the mouse on the scroll bars. A simpler method and what many consider the best method to navigate over smaller distances of a schematic is mouse panning. In mouse panning, you click and hold the right mouse button while dragging the mouse. The effect is like sliding a piece of paper across a desktop in the direction of the mouse movement.

Centering uses the SHIFT+right click method to navigate. While holding down the SHIFT button, click the right mouse button at the point that you want centered in the window. Clicking toggles the scale between 1:1 and 1:4 and centers the schematic at the mouse position. A useful situation for this method is when you have a large schematic that you are working on at a 1:1 scale. A single SHIFT+right click will shrink the schematic to a 1:4 scale. You can then visually scan the schematic to see the part of the schematic that you would like to work on next. Another SHIFT+right click on that part of the schematic will center it in the window at a 1:1 scale.

Place flags at locations you expect to revisit in the schematic through the Flag mode. Enter Flag mode, and then click in the schematic. A text dialog box will appear that lets you define the name of the flag. Once a flag is placed, clicking on the flag icon in the lower right window corner will display a list of all of the flags that are in the schematic. Choosing one of the flags from the list will center the schematic window on that flag. This method has the bonus of working between different pages of the schematic.
