News:

Effective 7/4/2019, Spectrum Software is closed. Micro-Cap is now free.

Technical support will be available for at least 90 days via email at Support.

You can download the latest versions of Micro-Cap here: Download
You can choose either the executable program or the entire installation CD for MC10, MC11, and MC12. If you have an earlier version, download and use MC12. These new versions do not require the security key, so they make Micro-Cap free to the entire engineering community.

Thank you for the honor and privilege of serving you for the last 39 years.

Direct Schematic Waveform Probing
 
Micro-Cap lets you probe schematics directly for waveforms. Simply point the mouse at a device or circuit node and click. You can set the probe to measure digital states, voltage, current, power, energy, resistance, charge, capacitance, flux, inductance, B field, or H field. The probe can display transient, AC, or DC analysis results. It's like probing a circuit with an oscilloscope, spectrum analyzer, or a curve tracer. Expressions such as VCE(Q1)*IC(Q1) to determine the power through the transistor Q1 may also be plotted.

Micro-Cap also supports hierarchial probing. Probe on a macro or subcircuit and up comes the macro schematic or subcircuit for further probing. Navigate levels easily.

SPICE files may also be probed by clicking on a part or node name within the text file.
