Are there any examples of a pad frame flow in openlane 2?
t
OL2 doesn't have any native support for pad frame generation. However you can easily create a custom step by extending OpenROADStep and provide a custom tcl script calling the appropriate OpenROAD commands. This is what we use in TinyTapeout for iHP november tapeout.

@tnt thanks, can you point me to that example?
t
Beware however that the whole rest of that repo might not be a great example. (1) TinyTapeout in general uses a very customized OL2 flow (2) Even more this was for iHP which is not supported in OL2 ATM so we're using custom PDK files and modified OL2 version ... So the padring part should be representative of what you have to do, but for the rest, don't be surprised if you see weird things.

No worries. I just started with OL2 last week so I'm mostly looking for examples. Thanks!

OR does support pad generation so hopefully you can get it to work in OL2
