    Default Can't display state machine states -- register holding state machine bit "|c

    What does this means?
    Warning: Can't display state machine states -- register holding state machine bit "|control|current_state.decR11" was synthesized away

    according to the help file, ask me to examine design file to search for the error. the prob is how can i detect the problem?

    what are you currently doing? a state machine? there must be something wrong with the flow of your state machine that causes your system to break its loop

    Hi,

    the warning indicates that the synthesis engine could remove the register from your design. Maybe the statemachine never reached this state ?

    Kind regards
