Hello all,
I have a connectivity issue in my layout hierarchy.
For demonstration I've recreated the problem of my layout in a few pictures.
The problem is with the connectivity of PIN's.
If I have 2 cells, each with a pin and I connect them together using intersecting metal, no connection is made.
The connection is only made if I draw a new connecting path/rectangle between the PIN's.
Why is the Layout tool not recognizing that it is connected ?

Top Layout (does not show connected although metal touches).

Does somebody know?
Thanks!
