Notes about the CIR file extension:

To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The CIR file type is primarily associated with 'PSpice' by Cadence Design Systems, Inc.. PSpice is a SPICE analog circuit and digital logic simulation software that runs on personal computers (thus the first letter P in its name). It was developed by MicroSim and used in electronic design automation. MicroSim was bought by OrCAD which was subsequently purchased by Cadence Design Systems. The name is an acronym for Personal Simulation Program with Integrated Circuit Emphasis. Today it has evolved into a analog mixed signal simulator.
