Hi,
to avoid problems in LVS you can use lvsIgnore, but this is only good for few elements like a pcapacitor. I would like to permanently have a series vdc=0 in my schematics, but to avoid lvs problems we need e.g. to replace the vdc with a short. I remember it is possible but forgot the details. Best would be having an analogLib element working for both stb analysis and lvs (but I found nothing so far).
Bye Stephan
