Hi alltogether,
I tried to do a simple layout (just an inverter-stage).
Everything worked pretty fine, the DRC didn't mention any error, but when
trying to do an LVS the logfile looks like this :

Any idea what's happening ?

I assume you are designing with an Infineon design kit.

In the Assura LVS GUI there is a field called 'Switch Names',
you have to set a switch with 'Set Switches'.
For your design kit you have to choose your process metal
options as switch.

Hope I explained it clear enough, but this is only an assumption.
