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.






When I step a parameter, how can I see which waveform goes with which step?


After a stepping operation, multiple waveforms will be available on the screen. To view which waveform belongs to which step, you need to invoke Cursor mode. This can be done by choosing Cursor, under the Mode selection of the Options menu or by pressing the F8 hotkey. The title of the plot will appear with the stepped parameter value of the waveform that the cursor is currently on. The title, when only stepping one parameter, will look similar to this:

PRLC.CIR Temperature=27 R1.Value=50

where the cursor is currently on the waveform produced when R1 was 50 ohms. To shift the cursor to the other steps, press the Up or Down Arrow cursor key.

You can also have Micro-Cap automatically label each waveform branch of the analysis with text. This is done by going to the Scope menu and choosing Label Branches. A text string describing the stepped values of the brach will be placed next to each branch. This is useful for branches that have some space between each other.
