A logic option that allows the Compiler to choose the signals that feed the most write enable and read enable inputs to memories as global write enable and read enable signals that are made available throughout the device on the global routing paths.

This option is ignored if it is assigned to anything other than a design entity. If you want to prevent the Compiler from automatically selecting a particular signal as global memory control signal, set the Global Signal option to Off on that signal. This option is available for All Altera^® devices supported by the Quartus^® II software except FLEX^® 6000, MAX^® 3000, MAX 7000AE, and MAX 7000B devices.
