Behavior
A probe is an element that simply displays the value at a given point in a circuit. It does not itself interact with other components.
In most respects, the probe component duplicates the functionality found in a Pin component configured as an output pin. The primary difference is that if the circuit is used as a subcircuit component, then an output pin will be a part of that interface, whereas a probe is not. They also are different in that the probe does not have a Data Bits attribute to be configured: The bit width is inferred from whatever value it happens to see on its input. Graphically, they are similar but have slightly different borders: A pin has a thick, black border, whereas a probe has a thin, gray border.
Pins
A probe component has only one pin, which will acts as an input to the probe. The width that this pin accepts is adaptive: The probe will adapt to inputs of any width.
Attributes
When the component is selected or being added,
the arrow keys alter its Facing
 attribute.
- Facing
 - The side of the component where its input pin should be.
 - Label
 - The text within the label associated with the component.
 - Label Location
 - The location of the label relative to the component.
 - Label Font
 - The font with which to render the label.
 - Radix
 - The base (for example, binary, decimal, or hexadecimal) in which a value is displayed.
 
Poke Tool Behavior
None.
Text Tool Behavior
Allows the label associated with the component to be edited.
