Scheme-it

Use schematic symbols to layout the components of your circuit and make electrical connections. With symbols ranging from amplifiers to vacuum tubes, as well as the ability to build custom symbols, you are able to design nearly any circuit. Access to Digi-Key's extensive part database also allows you to browse and assign orderable part numbers.

Use the system blocks to refine your idea at a conceptual level. The higher-level components are there to help you plan out the broader intentions of your idea. This powerful block chain library allows you to quickly layout the function of circuit. Once your design is ready, save and share with your colleagues.

The flow chart creation option will help transition your concept to a design. Use the library of arrows, shapes, UML symbols, and more to sort out the flow and annotate each stage. Insert a textbox, math function/formula, image, or link to help illustrate the objectives and make your plan easy to follow.
