INFO:Xst:2117 - HDL ADVISOR - Mux Selector <fchsta> of Case statement line 873 was re-encoded using one-hot encoding. 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 <fchsta> (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
