Quartus

Design Assistant warning: <Clock signal source should drive only input clock ports>. Found <number> nodes related to this rule.


CAUSE: In the current design, the Design Assistant found the specified number of nodes where you connected a clock signal source (for example, an input clock pin) so it drives both input clock ports and ports that are not input clock ports. However, you should connect a clock signal source so it drives only input clock ports of registers. The submessage(s) of this message list the node(s) that the Design Assistant found.
ACTION: Remove the connections between the clock signal sources and any ports they drive that are not input clock ports of registers.
