.cyprj file only does not give the enough information of the issue. You may refer to PSoC4 hardware design guide application note for analog routing design.
Can you please post your complete project or a shortened version that shows the error so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
There are a couple of errors when I compile your project although I do not get your mentioned error message.
When you double click on the error shown in the "notice" window the cause will be highlighted in red.
There are some pins configured as output which are not connected to a signal. When you want to set the pin by software you need to remove the "hardware connection" in the configuration.
Some signals are driven by more than one source.
The source of the clock for a component cannot be an IO pin.
Some inputs for components do not have a signal attached.
When you explain a bit more in detail what you want to perform someone in the forum will give you all the help you need.
I cannot open your project archive. Can you please try:
in Creator delete the folder "Generated Files" (just to keep the archive small)
Use Build -> Clean Project
File -> Create Workspace Bundle (Complete)
and then attach the generated .zip
