In the current design, the Design Assistant found the specified number of nodes where you did not specify a clock signal as a global signal. However, all the clock signals should be global signals. This warning can occur when you use more clock signals in the design than you can specify as global signals. The submessage(s) of this message list the node(s) that the Design Assistant found.

This rule applies only to designs that the Fitter has processed during a compilation. If you do not specify a clock signal as a global signal, but you turn on the Auto Global Clock logic option for the design, the Fitter can automatically choose the clock signal as a global signal. If the Fitter chooses all the clock signals as global signals, this warning does not occur.
