In my design with 5 cores I have a Placement blockage around each core. This was suggested by Kari to stop sroute from connecting all follow pins together. But now CTS and also nanoroute stops routing all signal that run from the cores trough the blockage to the IO pads.
I though its a placement blockage and not a routing blockage. Trial route works fine, but produces a lot of violations. What can I do to
allow nanoroute to pass trough the placement blockage?
I think it has to do with the following error:
NET $net is marked as fully connected but pin $pin of instance $instance is not yet connected.
This is repeated for all toplevel nets going to the IO cells. How can I reset these nets, so that they will be routed again?
