Invert the signal

i used to not gate to invert the waveform. But i got this error:Your schematic contain unknown model 74hc14"

Could you please suggest me any option for performing the inversion operation.

Dear Bosco,

Please select the component present from eSim_* libraries.(eSIm_digital, esim_subckt.....)

The component used 74hc14 is not ngspice compatible.

Second option:

If you have any spice model library file for 74hc14 , then you can change its reference "from U to X" if it is a subcircuit to "U to D" if it is a device model
