Hi everyone, how to configure openroad flow to generate only vertical straps of PDN ? I have tried to limit the metalization up to met4 using export MAX_ROUTING_LAYER = met4 without effect. The other thing I have tried was to comment the line which defines the horizontal strap in pdn.cfg file

I'd like to be able to do this as well. I can create only horizontal straps using only the top metal layer (just by only specifying that layer as a strap in the pdn.cfg, and providing the appropriate connections & blockages), but obviously that's not actually any help in distributing power around.
