Poke Tool

Behavior

The Poke Tool is for manipulating the current values associated with components. Clicking user-defined component reveals a magnifiying glass that can be clicked to reveal the inner state of that subcircuit. Clicking a wire segment using the Poke tool displays the value currently carried by the wire. The is particularly useful for multi-bit wires, whose black color provide no visual feedback about what value the wire is carrying.

Hint: For multi-bit values, you can configure how values are displayed (in binary, decimal, or hexadecimal, for example) using the Layout pane of the Logisim Preferences dialog box.

For other components, the precise behavior of the Poke Tool varies depending on which component is clicked; this behavior is documented in the `Poke Tool Behavior' section of each individual component. The following components all have support for the Poke Tool.
