The problem? Modeling large systems with modules with large I/O (DSPs or something else) and verifying those things is hard and not well suited for a complex verbose language.
Fight me, but I really think a mathworks simulink type visual modeling environment is a better way to approach this problem (and I hate mathworks with a passion, this isn’t a plug for matlab). That type of environment coupled with a way to generate high quality HDL is what I really want. I know mathworks has HDL coder and it’s ok, but still doesn’t quite do everything and you have the pay the enormous mathworks fee and can’t crowdsource platform updates as well as a well managed open source project might be able offer.
So when I see stuff like this I think “cool” but also “why???”
