Figure 7. Dense overlapping regulon.
Two simple regulations with combinational logic-based junctions (S[Y1] and S[Y2]) are within the same state (X1X2X 3 = 111). While the superstate (X1X2X 3) is active, two statecharts (each involving Y1 or Y2) are executed in parallel. It is not shown in the figure, but the signals that determine S[Y1] and S[Y2], based on combinational logic, are Sx1, Sx2, and Sx3.
