MAX_AUTO_GLOBAL_REGISTER_CONTROLS
Allows the Compiler to choose the signals that feed the most control signal inputs to flipflops (excluding
clock signals) as global signals that are made available throughout the device on the global routing paths.
Depending on the target device family, these control signals can include asynchronous clear and load,
synchronous clear and load, clock enable, and preset signals.If you want to prevent the Compiler from
automatically selecting a particular signal as global register control signal, set the Global Signal option to
'Off' on that signal.
