Hello,
I just discovered (hopefully before production) that the net planes (like ground) doesn’t check if them are all connected. I am putting a pic to explain it better:
Watch this gnd plane: the plane in the middle is not really connected with the remaing part and the DRC doesn’t give any error about it
Wouldn’t be a good idea to enable this check?
DRC normally checks this when running “list unconnected”. Is there a plane on the second layer? (After all there is a via so i guess the connection happens through there)
there is a track so yes the connection happens anyway, but, correct me if i am wrong, there is a big difference between connecting gnd trought a small track or trought a plane
DRC checks if any given parts are connected with each other. And if the minimum width requirements of the netclass are met. It is not a simulation engine.
There are no electrical connections that do not match the netlist, At present it does not look for floating copper, it trusts your ground via to be connected to something reasonable,
To flip it around, how would you define a 95% reliable method to tell that you have problematic floating copper, how large is too large, is it total area, or distance? etc.
DRC checks for floating copper. Floating means not connected after all.
