I am getting antenna errors like
```Cell: _41481_
Antenna violation detected at plane metal3
Effective antenna ratio 450.179 &gt; limit 400
Gate rect (65706 120815) to (65736 120943)
Antenna rect (75012 122980) to (75018 123044)```
is there any way to jump to that cell / net

The coordinates here should probably be better presented in physical units.  What you're seeing is internal units relative to the topmost cell.  You can find the gate, for example, by bringing up the layout and doing
`snap internal ; box values 65706 120815 65736 120943; zoom box`

Nets are not labeled because they would be implemented as labels, and magic has a very poor database implementation for labels (on my to-do list) that will slow certain commands down. . . a lot.  If it's a relatively small digital block, you can get away with changing the DEF read-in command in OpenLane to `def read -labels` so that the nets will be tagged with the same net name as in the DEF file.

Is there any way to jump to a cell by the instance name?

What is Linen?
