AUTO_GLOBAL_REGISTER_CONTROLS
AUTO_GLOBAL_REGISTER_CONTROLS
Type
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.
