I've tried 1) '0/'1: leads to magic-klayout XOR errors and some lvs errors of the pad frame 2) VSS/VDD: leads to lvs errors for short-connect the power grids. Thanks for your help! ``` **Attachments** - Resolved media URL: https://discord.wafer.space/wafer-space/%E2%84%B9%EF%B8%8F%20-%20Information/%E2%81%89%EF%B8%8F-questions/generate-clean-padring/2025-12/2025-12_media/image-91E0C.png

Therefore you cannot connect any constants to the pins (you can, but there will be no connections). You need to manually tie these pins after the GDS for the padring has been generated. ```
