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 - Fall 2015


This section is designed to highlight features that may be overlooked among the many capabilities of Micro-Cap.

Using the Plot Feature
Did you know that you can plot the characteristics of certain components from the dialog box used to place them? This is especially useful with independent sources whose waveform you're trying to create. Here for example is the plot for an FM source:

Source Plot

You can tweak the parameters and the plot responds.

To get a plot, all you need to do is click on the Plot button. For more complex devices you may want to first select the plot type you want as some devices have up to four types of plots. The BJT device for example, has four plots: IC vs. VCE, DC Current Gain, VCE Saturation Voltage, and Beta vs. Frequency.

Note that the plots only work for device primitives. If the part model is a power MOSFET it may be modeled as a subcircuit rather than as a NMOS primitive. In this case no plot will be available.

Note also that the plot is generated using the current settings for the necessary analysis mode. For example, a plot of an independent voltage source would use transient analysis and its current Time Range. Press F9 to get an abbreviated Analyis Limits dialog box where you can change the settings.
