CD4069 oscillator in LT Spice

I forgot to mention that the left circuit does not want to work.


Thank you, now it's working. Stupid me was trying to rename the GROUND node. But on the schematic shown by Bordodynov's (#53) I do not see any Vss node and the gate is working just fine.

The model used to explicitly refer to global node 0. Using a labels for the implcit supply rails is a more general solution. If you open the symbol in the Symbol Editor, do a Ctrl-A or Edit Attributes you will see on the "Spice Model" line either "VDD 0" or "VDD VSS". The "Value" will contain the name of the subcircuit e.g. "CD4069UB". Like this:



So this method will also work if you replace the label VSS with a 0. The 0 is a way to specify global node 0, aka ground, but it is less general.
