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 highlights a few features with each issue that may be overlooked because they are not made visually obvious with an icon or a menu item.

Renaming Component Names
Ever create a schematic and, after numerous deletions and additions, find that the parts are not named sequentially like R1, R8, R11? If you are like most engineers, you may want to tidy up the schematic by renaming the parts. Other than manually changing the names is there another way? Yes there is. Select Edit menu / Change / Rename Components and Micro-Cap will rename the parts according to the usual naming convention; R for resistors, C for Capacitors, etc. It scans the parts from the upper left to the lower right by rows and renumbers all of the resistors a R1, R2, R3,... then all of the capacitors as C1, C2, C3... and so on for each part type.

Connecting Nodes Together
To connect one node with another you normally drag between the nodes. Sometimes this is inconvenient, and occasionally impossible when the nodes are on different pages. What to do? Use text to connect the nodes together. The same text placed on two schematic nodes connects them together. It is as simple as that. Placing text on a node labels or names the node so that it can be referenced in an expression, such as when you want to print or plot V(OUT) or simply use it in another expression.

Locating Parts in the Component Library
When you want to know if there are any thermistors in the library you could simply browse the Component menu and see if there are any included. An easier way is to use the Find Component command. This command can be found on the Component menu, but it is more readily invoked by SHIFT + CTRL +F. This invokes its dialog box from where you can search the entire Component library by field for any text. In this case you would type in "thermistor", then click on the All button to search all fields of the Component library, and then click OK. This produces a list of part names that have the text "thermistor" in one of their field names. The list itself can be placed in a text file for later use of you can simply select one of the part names from the list.

You use this command to locate all parts whose Name, Shape, Definition, and / or Comment field text matches your search string.
