Actually at the bottom not that many features are required, basic is simple: - Graphical symbols with pins. - Possibility to connect pins or more abstract connection points. - Buses to bunch together like wires in a cable. - Possibility to assign values to objects. - The connections will form nets. Workflow specific: - Which graphical symbols should be available. - Attribute assignment. - Design rule check which may be done online. > ... Make it modular so that it doesn't become bloated. The basics above could be used for schematics of many types, electric, hydraulic, some software diagrams like VHDL and probably more. > > I came to the conclusion gschem is very versatile with quite little > > missing but something is missing.
