Why I will get "No model specified for U1" error in Proteus?

Hello there!

Thanks for reaching out.

Unfortunately, our models cannot be simulated on Proteus, but you may try going to the component's properties and checking the "attach hierarchy module". Note that this still generates minor errors and might not work for some applications.

You may also try downloading the simulation model available under the "Simulation Models" tab on the part page, or reach out to the manufacturer to request the spice model for this part.

Please let us know if this helps, and if you have any other questions don't hesitate to ask, we're here to help!

Have a great day,
