The first node is the highest-level (or root) node. It provides an input field for specifying a descriptive name for the design. The node Design-components provides the means for adding, deleting and editing design components. Right-clicking the icon of this node displays a short-cut menu for carrying out these actions. The components of the device are represented by sub nodes of the Design-components node. The properties of a component are specified in the data-input pane by first clicking its sub node. Related component data are grouped under different tabs (Geometry, Material and Display options). The displayed design in the System-view window is continuously updated as you change the components’ inputs. Try making some input changes to some components under the Geometry and Display options tabs and observe their effects on the displayed device.

 Also notice the specification of a loop field in the Applied field inputs and the choice of two outputs in the Output curves inputs. The Views node offers convenient means for displaying different views of the device and interacting with them.

 You start a simulation by clicking the Run button (you also use this button to halt an ongoing foreground calculation). Checking or un-checking the Run in background box, specifies if a calculation is to be carried out in the background or foreground. When a foreground simulation is running, you cannot do anything else with SVB until the calculation concludes. Background jobs execute behind the scenes, freeing you up to use the SVB software normally. A tool for monitoring the progress of background jobs is discussed in the section Program Menus below.
