Hi OpenLane team, I have congestion problems (well who doesn't) mainly between SRAMs. Is it possible to define classical "do-not-place-areas" for cells ? If not, any plans to add it ? Thanks in advance, cheers, Tobias

providing test case will helpful for debug. Try HALO/CHANNEL spacing around SRAM Macros

Thank you for your reply. The question is not related to a bug. It is about a common P&R feature and a more general question. So therefore no testcase or debugging is needed. I assume that HALO/CHANNEL spacing is not relevant here, as it solves other problems. Thanks again.

P&R done by OpenROAD App. So please create your discussion here: https://github.com/The-OpenROAD-Project/OpenROAD/discussions
