LOGICSIM MENUS

Apple menu

About LogicSim… 
Displays information about the price & the author.

File menu

New
Create a new document.

Open…
Open a document (from any 2.x version, not 1.x).

Close
Close a document.

Save
Save a document.

Save as…
Ask for a file name and save a document.

Page setup…
Display a dialog to set printing parameters.

Save as PICT…
Save the window contents in a PICT file.  PICT files can be edited by standard drawing programs and can be imported into most word processors.

Print…
Print a document (its circuit drawing).

Preferences…
Define actions associated with double-clicking components.  Also whether stimuli are listed in the Info window.

Quit
Quit LogicSim.

Edit menu

Undo
Available to undo the actions of Cut, Clear or the delete key.

Copy, Cut, Paste, Clear, Select all
Standard Macintosh commands.

Circuit menu

Redraw
Redraw the entire drawing window. May be useful after erasing some items.

Component delays…
Show a dialog where the pin delays for the selected component can be entered.

Component options…
Show a dialog where some parameters of the selected component can be changed.  This dialog depends on the component or module. Most components have no parameters, so this command is not available. Clock components are a notable exception and this is the way to set their period.

Component name…
Show a dialog where you can type a name to identify the selected component on the circuit.  If the first character is  '~' then the component name is written with a bar over it on the circuit, the conventional means of indicating negation.

Create module…
Create a new module.

Load module…
Load a module or component onto the end of the pallet on the left of the current circuit window.

Display family names
Devices belonging to a family of delays can have their names displayed, or not.

Create new family…
Create a new family of delay definitions

Modify family…
Change the definitions of delays in an existing family

Simulation menu

Options…
Show a dialog where you can set:
- Delays: which delay mode to use for the simulation
- Initial node values: (this should be X under normal circumstances)
- Simulator clock rate: the speed of the simulation in the real world
- Auto advance delay:  advance the signals record each time an input is switched
These options are explained further in the chapter on Advanced Features.

Run
Start the circuit simulation.

Stop
Stop the circuit simulation.

Reset
If the simulation is running, restart it with the initial node values.

Pause
Stop temporarily or proceed.

Show input values
Display the values of input pins on the simulation drawing.

Show output values
Display the values of output pins on the simulation drawing.

Show internal values
When unchecked the real node values are displayed, when checked the internal values of components are displayed.  The internal and external values will generally differ as a result of delays.  However, if the simulation is stable (i.e. nothing is changing), the two display modes will give the same results.

Record
Stop/restart the recording of the LEDs/switches/buttons/clocks values in the Signals Window.

Execute Stimuli
Start executing the program of stimuli associated with the running simulation.

Windows menu

Each available window is listed and can be opened and brought to the front by selecting it.
