Simulator Animate Button

The animate button will cause simulation to repeat the step command once per second until one of the following occurs:

the end button is pushed,
no signals will change within the simulated circuit,
the simulation time limit is reached,
or the simulation stops or pauses as a result of the action of the stop or pause elements in the circuit.

The amount of simulated time for each second of animation is controlled by the value showing in the Step field. This value can be changed any time the simulator is not running, with the new value becoming the step amount for the next animation.
