Editor tour

The menus, toolbars, dock and panels of the Sim Lab editor.

The editor is a full-screen workspace. Here is what each part does.

The Sim Lab editor
Top bar and menus, action bar, canvas, Inspector on the right, and the tool dock along the bottom.

Top bar

Shows the circuit name and these menus:

MenuWhat is in it
CircuitNew blank circuit, Open from text, Restore last session, Solve DC operating point, Full screen
EditUndo, Redo, Cut, Copy, Paste, Duplicate, Delete, Select all, Rotate, Flip
PartsEvery part, in groups (see below). Also Create a subcircuit and Manage subcircuits
GraphsStack, Unstack, Overlay, Separate
ViewWhat to show, plus Settings and Keyboard shortcuts
ExamplesReady-made circuits, including a Maestro group

At the right are search, a theme toggle and About and licence.

The Parts menu

The Parts menu
The Parts menu lists parts in groups.

The groups are Passive parts and switches, Sources, Meters, displays and labels, Arduino and board parts, Semiconductors, Op amps and building blocks, Logic gates, Digital chips and memory, Mixed-signal chips and Subcircuits. Under them: Create a subcircuit…, Manage subcircuits…, and the Select, Pan the view and Move the selection tools.

The Edit menu

The Edit menu
The Edit menu: undo, clipboard, duplicate, rotate and flip.

The View menu

The View menu
The View menu switches parts of the screen on and off.

Tick or untick Current dots, Voltage colours, Power view, Values on parts, Dot grid, Graphs, Inspector, Action bar, Tool dock, Minimap and Light theme. Settings… has more options, such as European resistor symbols, IEC gate symbols and the direction of current. Keyboard shortcuts… lets you change shortcuts.

Action bar

Undo and redo, cut, copy and paste, duplicate, rotate and flip, delete, then Running or Stopped, Reset, Freeze and Speed.

The dock at the bottom

Quick tools: Select, Hand (pan), wire, resistor, capacitor, inductor, diode, voltage source, ground, switch and op amp. Then a magnifier to search all parts, ICs, Instruments, and a pin button for grading points (hidden in exams).

To place a part, press and drag its button onto the canvas.

The part search box
The magnifier opens a search box. Type a part or a command.

Inspector (right)

Shows the simulated time and time step, the speed of the current dots, and Live controls, where sliders for potentiometers and other adjustable parts appear. Click a part to open its properties.

Graph strip and zoom pill

Scopes appear along the bottom. The zoom pill (top right of the canvas) has zoom, buttons to hide the graphs and Inspector, and the Help button. A minimap appears when part of your circuit is off screen.

Help

Press the ? button for Help. It's searchable and has a 1-minute Take the tour.

The Help panel
Help is searchable and has a short tour.

Examples

Open Examples for ready-made circuits. The Maestro group has a welcome LED-matrix demo and a dot-matrix display.
