@User So ... can you confirm that power distribution isn't yet really supposed to work in

develop

? 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.

Have you managed to work this out?

I mean, I got something that I think works for me. What I ended up doing is : • Still have

met5

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.

Ah, I see, so you are matching the pitch to get the straps to align.

yeah. If I didn't have SRAMs I could have just disabled

met5

streaps on the inside and exposed all the

met4

streaps as power pads and let the top level connect to them.
