### Switch On ###
In Logisim there is no real switching on" of a circuit. The circuit is working also while you are modifying it.
In Logisim there is no real "switching on" of a circuit. The circuit is working also while you are modifying it.
This causes sometimes an unexpected behaviour. A simple master-slave flip-flop
can not be realized with Logisim, since the circuit is not switched on, there is no
settling time to bring the circuit to a stable condition after its completion.
A master-slave flip-flop can only be implemented with a reset input. This
A master-slave JK-flip-flop can only be implemented with a reset input. This
reset input needs to be activated to make the circuit operational.
To understand how Digital deals with this issue, you have to look at how the simulation works in Digital:
