 MIF-ERROR - unable to find definition of model u1
Warning: Model issue on line 14 :

Unknown model type inverter - ignored
Reducing trtol to 1 for xspice 'A' devices



This error is coming on ngspice window when i am simulating the circuit containing component which i have uploaded using nghdl feature. Here u1 is the component which i have uploaded using nghdl.

Answers:

Please follow the instructions of VHDL file that needs to be uploaded. It accepts only bit and that too in std_vector. If other versions then, you need to use VHDL signal conversions
