Electronic WorkBench (EWB) is a simulation package for electronic circuits. It allows you to design and analyze circuits without using breadboards, real components or actual instruments. Here you can find various workbench tools like screwdrivers, Allen keys, wrenches, etc. EWB’s click-and-drag operations make editing a circuit fast and easy.

In Electronics Workbench every circuit you draw is automatically ready for simulation, so you can begin testing at the earliest possible stage of the design flow during schematic capture.
