Auto Global Clock logic option

Allows the Compiler to choose the signal that feeds the most clock inputs to registers as a global clock signal that is made available throughout the device on the global routing paths.

This option must be assigned to a design entity or it is ignored. To prevent the Compiler from automatically selecting a particular signal as global clock, set the Global Signal option to Off on that signal. This option is available for all Intel devices.
