I am trying to calculate the capacitance of a Josephson Junction (a sandwhich of superconductor - isolator - superconductor) but Q3D is giving me a validation error (Net 'SignalNet1': Incorrect net. Net should contain a completely connected conductor). I have assigned nets to my superconductors but not to my nonconducting isolator. Does anyone know how to handle this error? I can't even seem to find the vaildation settings (Electronics Desktop 2023 R1).

Thanks for any advice!

 Hi Tabea,

 

This error appears in Q3D during the Validations.

 

The possible cause of the error is if the SignalNet1 has unconnected conductors. The Net represents the logical connectivity defined in the schematics and may have signal traces, vias connected. Please consider this as an example. If there is slightest gap in the geometry for example if via is not touching to top traces even by um separation and even if one forms a net representing trace and via together. The above error appears in Q3D validations. To mitigate the error, make sure that every geometry which is a part of Net has electrical connectivity.

 

Thanks,
