9.2i XST - FSM is not encoded by XST when there is no initial condition


I coded to infer two FSMs in the code, but XST encodes only one FSM.

What causes this problem?


XST can infer an FSM only if there is a power-up state or reset condition; when this is not the case, XST cannot infer an FSM. Refer to the ISE Language Templates for examples of coding state machines with reset conditions.
