1.10.12. AUTO_GLOBAL_CLOCK

Allows the Compiler to choose the signal that feeds the most clock inputs to flipflops as a global clock signal that is made available throughout the device on the global routing paths. If you want to prevent the Compiler from automatically selecting a particular signal as global clock, set the Global Signal option to 'Off' on that signal.
