8 years agoAuto global has nothing to do with the issue you are seeing. That just tells the compiler to make use of the global clock resources in the device to distribute your clock signal. If you turn that off, either you have to assign clocks to global resources manually in the Assignment Editor or the compiler will just use local routing (instead of global) for your clock. The real issue (which is impossible to tell because your screen cap is too small to see) is if you have connected a clock signal to your design correctly, in the design itself and in the Pin Planner.
