Electric is a sophisticated electrical CAD system that can handle many forms of circuit design, including custom IC layout (ASICs), schematic drawing, hardware description language specifications, and electro-mechanical hybrid layout.

The system includes many tools for analyzing and synthesizing circuitry.

Electric has an unusual way of doing integrated circuit (IC) layout. The system considers integrated circuits to be composed of nodes and arcs. Nodes are circuit elements such as transistors and contacts. Arcs connect the nodes. This enables layout constraints to be added to the arcs.
