The Simulate menu

Simulate Enabled

If checked, circuits viewed will be ``live:'' That is, the values propagating through the circuit will be updated with each poke or change to the circuit.

The menu option will be automatically unchecked if circuit oscillation is detected.

Go Out To State

When you delve into a subcircuit's state via its pop-up menu, this menu lists the circuits above the currently viewed circuit's state. Selecting one displays the corresponding circuit.

Go In To State

If you have delved into a subcircuit's state and then moved back out, this menu lists the subcircuits below the current circuit. Selecting one of the circuits displays the corresponding circuit.

Ticks Enabled

Starts automatically ticking the clock. This will have an effect only if the circuit contains any clock devices (in the Base library). The option is disabled by default.

Tick Frequency

Allows you to select how often ticks occur. For example, 8 Hz means that ticks will occur eight times a second. A tick is the base unit of measurement for the speed of clocks.

Note that the clock cycle speed will be slower than the tick speed: The fastest possible clock will have a one-tick up cycle and a one-tick down cycle; such a clock would have up/down cycle rate of 4 Hz if the ticks occur at 8 Hz.
