I have a SPICE text file from another program that I want to analyze in Micro-Cap. The name of the file is RINGDIF.CIR. Whenever I try to load this in Micro-Cap, I get an error stating that I "Must run CONVERT for 'RINGDIF.CIR' to force a conversion." Is it possible to analyze a SPICE text file?
Both SPICE and PSpiceŽ text files can be run directly in Micro-Cap. The problem in this case is the extension of the file RINGDIF.CIR. Micro-Cap assumes that any file with the extension .CIR is a schematic file, and since it doesn't recognize the SPICE file as a compatible schematic format, it returns the convert error. The procedure for fixing this is simple. Just change the extension of the file to .CKT. The file RINGDIF.CKT would be able to load and run without a problem. This only applies to complete SPICE circuit files.
