Global nets

Question

Hello,

I am designing the multi-page schematic and I would like to pass some signals from one page to another ( the same with the the supply nets and GND ). When I tried to generate the the output I get the warnings. Could you help me to understand how to solve those warnings.

This violation occurs when a net in the design has been detected to have no driving source. That is, the net does not include at least one pin with one of the following electrical types:

IO
Output
Open Collector
HiZ
Emitter
Power

Pin type definitions are generally done in the library, but can be modified on the Schematic.

This is also a fairly common warning to receive if you use passive pins a lot in your design. Not necessarily something you need to worry about unless you are being meticulous about pin type definitions.
