2.Structure of Alternative Divergence

When the individual condition at the current status is true, the step will be transferred to another individual step. For example, when X0 = ON, S20 will be transferred to S30; when X1 = ON, S20 will be transferred to S31; when X2 = ON, S20 will be transferred to S32.

3.Structure of Simultaneous Convergence

Consecutive STL instructions construct a simultaneous convergence structure. When the transition condition is true after continuous steps, the operation will be transferred to next step.
