説明

Description

As stated in title, currently OpenROAD doesn't support multi-cut vias which could be a crucial functionality as shown in the figure below.(In FlewPR.cpp) So I believe it's impossible to set constraint in ndr rule for multi-cut vias since it's basically not support in the OpenROAD router.

Suggested Solution

Further modification need to be done for the router or create a new router just for multi-cut vias.
