Intialization of State machine

[john]

Hello,

I saw the code of many state machines in different books, intializing
the state machine's register with the help of Asychncrounous external
RESET . How the state machine resgister will be intialized, if there is
no externel RESET available. Please advice!

Thanks
Regards
john

You need to identify an event that starts the fsm regardless of its
state, than ensure that this event is processed in every _possible_
state (especially in the netlist). Else you need to introduce such an
event (e.g. synchronous reset).
