one feature is very usefull for teaching digital electronic (gate, flip-flop, ...) ; this is pseudo-real time simulation... some software support this like Proteus. I really think that
Qucs should also add this killer-feature. I know that it's a hard work to do...
Maybe you should also support "applications" like in
so it could be possible so see both the electronic and the system that is
connect to the electronic board
So it will be like the interaction between grafcet and the system with IRAI
Automgen and IRIS 2D or IRIS 3D objects
