How to simplify hardware design

You certainly have done a good GUI and spent a lot lot of time to get to that stage. My first point is this "could there be a bug in the idea itself?".

my second point is this: is it verilog or boxes? if boxes then what is diffeent from schematic? Or do you mean you design by boxes but can simulate boxes or verilog?

Beginners = Uni students and are tied up to their professors choice. However, I do wish you success seriosly because you are far more creative than many of us.
