There are other generators built into Electric. These commands (in menu Tool / Generation) may be used:

- Coverage Implants Generator Although individual MOS nodes and arcs have the proper amount of implant around them, a collection of such objects may result in an irregular implant boundary. To clean this up, you can place pure-layer nodes of implant that neatly cover the implant area. This command does it automatically. It removes previous pieces of coverage implant before running, so that the result is a clean cover.
