- <dl>
- <dt><strong>Simulation Enabled</strong></dt>
- <dd><p>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.</p>
- <p>The menu option will be automatically unchecked if
- <a href="../prop/oscillate.html">circuit oscillation</a> is
- detected.</p></dd>
- <dt><strong>Reset Simulation</strong></dt>
- <dd><p>Clears everything about the current circuit's state, so that it
- is as if you have just opened the file again. If you are viewing a
- subcircuit's state, the entire hierarchy is cleared.</p></dd>
- <dt><strong>Step Simulation</strong></dt>
- <dd><p>Advances the simulation one step forward. For example, a signal may end up
- entering a gate during one step, but the gate won't show a different signal
- until the next simulation step. To help identify which points in the overall
- circuit have changed, any points whose values change are indicated with a blue
- circle; if a subcircuit contains any points that have changed in it (or its
- subcircuits, recursively), then it will be drawn with a blue
- outline.</p></dd>
- <dt><strong>Go Out To State</strong></dt>
- <dd><p>When you <a href="../subcirc/debug.html">delve into a
- subcircuit's state</a> via its pop-up menu, the <q>Go Out To State</q>
- submenu lists the
- circuits above the currently viewed circuit's state. Selecting
- one displays the corresponding circuit.</p></dd>
- <dt><strong>Go In To State</strong></dt>
- <dd><p>If you have delved into a subcircuit's state and then moved
- back out, this submenu lists the subcircuits below the current
- circuit. Selecting one of the circuits displays the
- corresponding circuit.</p></dd>
- <dt><strong>Tick Once</strong></dt>
- <dd><p>Steps one tick forward into the simulation. This can be useful
- when you want to step the clocks manually, particularly when the clock
- is not in the same circuit that you are currently viewing.</p></dd>
- <dt><strong>Ticks Enabled</strong></dt>
- <dd><p>Starts automatically ticking the clock. This will have an
- effect only if the circuit contains any clock devices (in the Wiring
- library). The option is disabled by default.</p></dd>
- <dt><strong>Tick Frequency</strong></dt>
- <dd><p>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.</p>
- <p>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.</p></dd>
- <dt><strong>Logging...</strong></dt>
- <dd><p>Enters the <a href="../log/index.html">logging module</a>, which
- facilitates automatically noting and saving values in a circuit as a
- simulation progresses.</p></dd>
