Call Telelogic if you want a complete solution including codegen (and can pay!). Cinderella is an SDL editor with simulator but no codegen - but has downloadable trial. There is a small French company whose name I can't remember which is doing an new SDL-style editor but with C++ syntax.
Thank you very much for answers. Cinderella is very interesting ide. But may be You know any free or cheap soft that can convert SDL diagrams in C++. Telelogic' soft may be good but it costs absolutely mad money.
That's what the 'mad money' is for: a complete code-gen solution that works. Non-trivial.
Haven't looked at ProgGen, but I expect that to execute the generated code there should be some sort of 'kernel' which executes the generated code with SDL semantics.
Connections to environment should be done through that.
Can you customise ProgGen? If you don't know, you've got a lot of work to do.
If my firm decide to buy something it will be ProgGen. It is cheaper that Telelogic in times. Telelogic doesn't understand that there are a lot of countries where people can't pay as much money as in the usa. And i suppose you know how we get software in countries like Polsha.
