How do I to create/export a custom netlist?

[Anonymous]

I've populated a lot of data fields for parts in my schematic that I'd like to export along with the netlist.  I see an option to export a netlist, but when I do it does not contain all the data fields I want.  How do I create and export a custom netlist?

Hello mcbalc,

I hope you're doing well. The netlist only contains net connectivity information. If you have defined a bunch of custom attributes the best way to get them is to use the bom.ulp that comes with EAGLE. Click on the ULP icon and then double-click (These are all left-clicks by the way) on the bom.ulp. You can export the information as a csv file and open it in a program like Excel for editing.

Please accept as solution if my post fully resolves or you issue, or reply with additional details if the problem persists

Let me know if there's anything else I can do for you.

Best Regards,

Thanks for the reply Jorge. I checked out the BOM function. Is it
possible to customize the BOM.ulp to pull in the Netlist or Pinlist
information on each respective part? It seems like that would give me what
I am after.

I looked at ulp's on the Eagle site and didn't find one that jumped out at
me as having this option. I don't mind learning to create one but I'm new
to this and just am not sure what's possible.

Hi Micah,

As far as I know there is nothing currently that produces a file with both pieces of information together. Board houses usually want them separated. You could definitely modify the ULP to get what you want, the syntax is basically C so if you're familiar with C/C++ you'll feel right at home.

The ULP language section of the HELP command is the full documentation on all of the functions supported by the ULP language.

Here is a webinar covering some of the basics:

Hi  jorge.garcia,

Where can I find the ulp file for the EAGLE Netlist?

Hi @Anonymous ,

I hope you're doing well. The EAGLE netlist can be exported by going File > Export > Netlist.

Let me know if there's anything else I can do for you.
