? Or am I missing something ? Because AFAICT it generates a giant grid met4
/ met5
and just completely goes over everything including the macro, shorting everything.Ahmed Ghazy

straps in my main block, but match the 180 pitch. I need them to power the SRAM
• Modify the LEF to expose all of them as power pads (also adapting obstructions)
• Align it in the user_project_wrapper
so that those pads overlad the right top level straps generated by the wrapper power grid. I also modified the PDN in the wrapper to only generate straps for vccd1
/ vssd1
since that's all I use. Rings are still generated for all rails. I also modified it so that met5
straps go over the macro, but met4
straps at the top level are 'cut'/interrupted.https://i.imgur.com/1GpQo5X.png▾

streaps on the inside and exposed all the met4
streaps as power pads and let the top level connect to them.
