Speed

The speed of the digital simulation is set under Options, Digital Options, Simulation speed. For counter circuits, a speed of 7 to 10 is appropriate.

Building counters with JK Flip-flops

 

Here is a synchronous divide-by-four circuit using a 7473 1/2 flip flop. The logic switch is set to 0 to reset the flip flops to zero and set to 1 to let them run:
