ID:284001 Cannot 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 Analysis & Synthesis to choose the best state machine encoding method.

ACTION: No action is required. Analysis & Synthesis 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.
