The case statement will be optimized (default statement optimization), but this optimization may lead to design initialization problems. To ensure the design works safely, you can:   	- add an 'INIT' attribute on signal <next_state> (optimization is then done without any risk)   	- use the attribute 'signal_encoding user' to avoid onehot optimization   	- use the attribute 'safe_implementation yes' to force XST to perform a safe (but less efficient) optimization    Using one-hot encoding for signal <next_state>.
