Spectrum Software
Industrial Strength Simulation




Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.






Whenever I try to go into analysis, I get an error that there is no such file or directory as "NOM.LIB", some other library, or a macro circuit. How do I get Micro-Cap to find the libraries?


Micro-Cap is looking in the path or paths specified in the Paths dialog box under the File menu. The way to fix this is to either move the library or edit the path in the Paths option under the File menu.

Click on the File menu and choose Paths. This invokes the Paths dialog box. In this dialog box, there is a field with the label 'Model library and include files'. This field should have the path pointing to the Library subdirectory under the main Micro-Cap directory. If you went through the default installation, the path would be:


The Library directory is the directory where Micro-Cap installed all of the libraries and macros that come with the program including the important NOM.LIB file. The NOM.LIB file contains the listing of all of the library files that Micro-Cap will try to automatically access. If you are using a library that is not listed in this file, then you must access it with a '.LIB' statement. The NOM.LIB is a text file and can be edited with any text editor.

In some cases, you may want to store your libraries in different areas of your hard drive. You may specify multiple paths in any of the Paths field by placing a semicolon between paths such as:


At least one of the specified model library paths must point to where the NOM.LIB file is stored.
