Can't choose best encoding method for state machine <name>


CAUSE: You set the State Machine Processing logic option to Auto; however, the logic of the specified state machine is too complex for the Logic Synthesizer to choose the best state machine encoding method.
ACTION: No action is required. The Logic Synthesizer attempts to process the logic using either one-hot encoding or simple binary encoding. To avoid receiving this message in the future, you might try simplifying the logic of the state machine.
