WebThe module enum_fsm is an example of a SystemVerilog state machine implementation that uses enumerated types. In Intel® Quartus® Prime Pro Edition synthesis, the enumerated type that defines the states for the state machine must be of an unsigned integer type. If you do not specify the enumerated type as int unsigned, synthesis uses a signed ... WebMar 19, 2015 · state==B && c -> $past (state)==A; means that if you're in state B and you have a c, it's because you were in state A. However, if the fsm is complex, there may be another path that caused you to be in state B, and then you get a c in same cycle. Thus, X -> $past (Y) means that if in X, its because you were in Y. In complex FSMs, i may see
