If I have some analog signals at the top level that I'm routing to a pad, how can I tell openlane to NOT add buffers to the wires?

Maybe this helps? <https://open-source-silicon.slack.com/archives/C016H8WJMBR/p1662463841735099?thread_ts=1662462922.036929&amp;cid=C016H8WJMBR>

<@U017X0NM2E7> which file of openroad should we add it ??

I have added inside the run_placement proc , but not seems to be recognized :

[STEP 7]
[INFO]: Generating PDN...
