sci-electronics The software tools in the Chipmunk system perform a wide variety of tasks: electronic circuit simulation and schematic capture, graphics editing, and curve plotting, to name a few. Here is a brief description of each of the Chipmunk tools. Log is a graphical environment for entering circuit schematics, and for analog and digital circuit simulation. View is a tool for manipulating and plotting data. Until is a graphics editor. Wol is a tool for creating integrated circuit layout. In addition to these major tools, many supplementary tools are part of the Chipmunk system.
