Library Reference

A Logisim library holds a set of tools that allow you to interact with a circuit via clicking and dragging the mouse in the canvas area. Most often, a tool is intended for adding components of a particular type into a circuit; but some of the most important tools, such as the Poke Tool ( ) and the Select Tool ( ), allow you to interact with components in other ways.

Frequently, when the component is selected or added, Alt-0 to Alt-9 is used to change its Data Width attribute. Quick use of the keys allows the entry of larger values, for example: ALT-1 ALT-2 donne 12.

All of the tools included in Logisim's built-in libraries are documented in this reference material.
