When in Free Select Mode, Virtual Breadboard supports drag-and-drop moving of the selected component or groups of components. Before moving components make sure the Breadboard is in Free Select (Click the Free Select Icon if not already selected, or just press the Esc key).
To drag and drop a component into position click-and-hold the cursor on the component you want to move. A move selection box will be attached to the cursor and the cursor will change in to a move (NSEW) cursor. Moving the cursor will move the outline of the component which provides a preview of where the component will be moved to. Releasing the mouse button drops the component to the new location.
Moving group selected components is also supported by the drag-and-drop move.
Finally, the circuit is complete and we are ready to run the simulation. Virtual Breadboard operates under two modes, design and runtime. So far we have been in design time mode. Design mode allows you to add new components, modify their properties, move them around the breadboard and so on. Runtime mode allows you to observe the circuit under simulated conditions.
Virtual Breadboard supports five basic runtime features: run, halt, step, step-over and reset. In addition to these features, components themselves may have runtime controls that will only be available when in runtime mode. The PIC16C54 for example has an entire debugging tool suite available during runtime to assist in the debugging of its source code.
In this example however, the source has already been tested so all you need to do is press the run button to start the simulation.
