Hi Vidhya,

We do not have a PSPICE model for the SN74HC20.

Hey Vidhya,

I created one for you. You can use this one to finish up your design.

SN74HC20.lib

HI Owen,

Tried converting the shared .lib to .olb

Seeing some error in simulation. Refer to the errors below.

Thanks and Regards,

Hi Vidhya,

The Subcircuit SN74HC20 is defined as the first real line in the .lib file.

Looking at this it seems the simulation you are running did not properly grab the .lib file that you had to build for this.

This video goes in depth about how to add a library to your simulation.

After doing that line 24 should have something like .lib "SN74HC20.lib" or something similar.

Regards,

Owen
