  16. <h2>Behavior</h2>
  17. <p>A probe is an element that simply displays the value at a given point
  18. in a circuit. It does not itself interact with other components.</p>
  19. <p>In most respects, the probe component duplicates the functionality
  20. found in a <a href="pin.html">Pin component</a> configured as an output
  21. pin. The primary difference is that if the circuit is used as a subcircuit
  22. component, then an output pin will be a part of that interface, whereas
  23. a probe is not. They also are different in that the probe does not have a Data Bits
  24. attribute to be configured: The bit width is inferred from whatever value it
  25. happens to see on its input. Graphically, they are similar but have slightly
  26. different borders: A pin has a thick, black border, whereas a probe has
  27. a thin, gray border.</p>
  28. <h2>Pins</h2>
  29. <p>A probe component has only one pin, which will acts as an input to
  30. the probe. The width that this pin accepts is adaptive: The probe will
  31. adapt to inputs of any width.</p>
  32. <h2>Attributes</h2>
  33. <p>When the component is selected or being added,
  34. the arrow keys alter its <q>Facing</q> attribute.</p>
  35. <dl>
  36. <dt>Facing</dt>
  37. <dd>The side of the component where its input pin should be.</dd>
  38. <dt>Label</dt>
  39. <dd>The text within the label associated with the component.</dd>
  40. <dt>Label Location</dt>
  41. <dd>The location of the label relative to the component.</dd>
  42. <dt>Label Font</dt>
  43. <dd>The font with which to render the label.</dd>
  44. <dt>Radix</dt>
  45. <dd>The base (for example, binary, decimal, or hexadecimal) in which
  46. a value is displayed.</dd>
  47. </dl>
  48. <h2>Poke Tool Behavior</h2>
  49. <p>None.</p>
  50. <h2>Text Tool Behavior</h2>
  51. <p>Allows the label associated with the component to be edited.</p>
