What is a CIR file?
A CIR file is a schematic created by Micro-Cap, an integrated schematic editor and simulator used by electronics engineers. It contains plain text data used to show a circuit diagram in Micro-Cap. CIR files can also be opened in any text editor to view the plain text data they contain.
More Information
In 1982, Spectrum Software released the original version of Micro-Cap. Micro-Cap is an application that electronics engineers use to model, simulate, and test electrical circuits. The most recent version of Micro-Cap, Micro-Cap 12, allows engineers to perform smoke and stress analyses, perform worst-case analyses, and adjust the temperature conditions a circuit is tested under, among other features.
Micro-Cap 12 and earlier versions save engineers' circuit models as CIR files. These files are plain text files formatted such that Micro-Cap can read and transform them into circuit diagrams. The first section of a CIR file, which contains the header [Main], details the file's type, the version of Micro-Cap that created the file, and various other metadata. The remainder of the file contains data used to show a circuit in Micro-Cap.
How to open a CIR file
You can open a CIR file in Micro-Cap (Windows). While Micro-Cap is no longer developed, the final version of the program, Micro-Cap 12, is available for free at Spectrum Software's website. To open a CIR file in Micro-Cap, select from the program's menu bar.
If you want to view the plain text data a CIR file contains outside Micro-Cap, you can open the file in any text editor.
