How to make a custom library part in Eagle CAD tool

Step 17 Naming Pins

As great a names as P$1-p$32 are it will make our lives easier when we connect pins on the symbol with pads on the package if we use a more intelegent naming shceme. We will assign the names of the pins based on, you guessed it, the data sheet.

Type name in the command window and double click on the pin to remain. A small dialog box will appear with the current name. Change the name and click "Ok". Repeat 32 times.

By default the name on the pin and the symbol will show up in the device. This makes for a very cluttered look. Click on the "change" button and select "visable" from the drop down menu, and then select "Pin". Then click on every pin. It will not be obvious what you are doing but trust me the final design will be easier to use.

If you can get a list of the pin names and numbers, you can make this easier with a script, as follows:
NAME P$1 PGND_1
...and so on; one pin per line.

A programmer's editor like UltraEdit or SciTE makes it easier to add the "P$" to the numbers. When you're done, save it as an ASCII text file with an .SCR extension and load it from Eagle's File menu. Easy peasy!

If you're bored with clicking and typing... You can just select the name option on the left and then in the command line, type the current name and then the new name you want for each pin
