Hello @vivek338,

just select the pin multiplexing you want to have via the "Pins Tool" and then export it via the menu. You can find some pictures in the appendix.

1) Configure your multiplexing by clicking on the specific pins in the CPU ball grid.

2) Or configure your multiplexing via interface selection in the left column.

3) Then export it.

4) Choose what you want to export.

5) Select your target directory.

I hope this helps.
