ALLOW_SYNCH_CTRL_USAGE
Allows the Compiler to utilize synchronous clear and/or synchronous load signals in normal mode logic cells. Turning on this option helps to reduce the total number of logic cells used in the design, but might negatively impact the fitting since synchronous control signals are shared by all the logic cells in a LAB.
