Easily Overlooked Features - Summer 2012


This section is designed to highlight features that may be overlooked among the many capabilities of Micro-Cap.

Converting schematics to older versions If you have MC10, you can load any schematic back to and including MC5. Can MC5 read an MC10 schematic? No it cannot, because there are options listed in the MC10 file that MC5 doesn't know what to do with. However, there is a way to convert an MC10 schematic file to any predecessor file from MC5 through MC9.

The command is located at File Menu / Translate / Schematic to Old Version. Its dialog box looks like this:

Translate dialog box

If you invoke the dialog box, it presents a list of file versions. You merely select the file format that you want and the path and file name that you want for the translated file, then press the OK button.

Here are a few things to keep in mind:

1) Always choose a file name that is similar but different from the original file. Otherwise you'll overwrite the later file in the earlier format loosing some of your options in the process. The circuit will still run but some MC10 options may be lost. For example, MC10 has a feature called Periodic Steady State that does not exist in earlier versions. Whatever settings (that are unique to MC10) you have in the original MC10 file will be lost in the translated file.

2) If the MC10 version had a component that was not available in the earlier version, then in place of that component, a message "Component Not Found" is printed instead. You can easily patch the translated file by removing the component and replacing it with its earlier equivalent.
