Question about GNSS component / checks for proper interference minimisation

[StohanzlMart]

Hello, love the idea behind the project. Though the only thing I cannot find is how to incorporate the info from Application Notes about placement (i.e. PA1616D GNSS Module), excerpt below.

Or how to put this text into the component model, or do I have to add checks to do that?

If the component can yield those constraints too (we had serious troubles with interference), I see no reason, why we don't buy your compiler & ui.

Hi @StohanzlMart

You have some good questions.

Starting with the last one first: you can define a portion of a ground pour as part of your landpattern for the device so that when you instantiate the device, you automatically instantiate the portion of the ground plane as you have defined it.

In terms of doing placement, I think that with the appropriate code, it should be possible to automate the placement as described in the application note that you reference.

For an example of a code placed module, please take a look at our cookbook example of a regulator here: https://github.com/JITx-Inc/jitx-cookbook/tree/main/regulator_example

With the appropriate introspection on component sizes and pad locations, you can also place components in a design as we did here: https://github.com/JITx-Inc/jitx-cookbook/tree/main/usb_c_cable_tester
