That is the output may change whenever the enable input is high. 5.23 State Machine 5.23.1 Netlist entry Axxxx [ in_0 in_1 .. in_n ] clk reset [ out_0 out_1 .. out_n ] model_name 5.23.2 Connection details Name Description Flow Type Vector bounds in Input in d, vector none clk Clock in d n/a 163 SIMetrix Simulator Reference Manual
