So, pretty much the problem is explained in the title.

I have placed in the schematic the ADC with 4 first inputs connected to Analog input pins and the rest are connected to the internal bandgap reference.

My project does not compile and the error I am getting is: "vinPlus_0" requires connection when it is visible. Same for channels 1,2 and 3.

Any suggestions?

Could you show the capture of topdesign?

I checked again the original project is built finely on my side. Attached here for your reference.

I don't see any error while building the attached project. The analog routing is fine.

However, there is a warning "Bonded pin(s) "P10[4], P10[5], P10[6], P9[7]" are not used in your current design but have been connected in order to route the design.".

It means these pins are borrowed for usage of analog routing from VBGR to vplus of some channels through AMux. These pins should not be used as analog I/O any more in your design.

Please see attached screenshot.

I am not using any of the bonded pins but I am still getting connection errors.
