Micro-Cap[1] is a SPICE compatible analog/digital circuit simulator with an integrated schematic editor that provides an interactive sketch and simulate environment for electronics engineers. It was developed by Spectrum Software, and was only available with a paid commercial license.[2] In July 2019, Spectrum Software closed down and Micro-Cap was released as freeware.[3] Software updates and technical support are no longer available. In early 2023, their website went offline, though it was previously backed up at archive.org.[4]
