VHDL . . . A wonderful tool isn't it. Until something goes wrong and no one knows why. This is a place we can talk about it. Why didn't this compile like you thought it would? Maybe another user can tell you. How does a construct work? Perhaps someone can explain it. Where can you find a good "student" (free) VHDL compiler? Why doesn't this meet timing? Bought a compiler and you feel the need to warn everyone that it chokes on big case statements? You just found something cool?
