4 years agoQuartus graphical toplevel(bdf) no error for missing source signal
The compiler brings no error for exsisting signals, even if they have no source.
Is there an option to enable compiler errors for such a case, if signals have no source.

4 years agoCan you provide an example of what you are looking for? If an input of something is not connected, the logic is usually optimized away if possible. You can prevent this by creating a virtual pin assignment.

4 years agoThank you for the reply,
the problem here was that the signal without source signal was not used, so it was not driving logic.
That's why the compiler saw no need to complain. That's now basicale fine for me.
I haven't checkt for warnings yet. I will do that.
It would be fine (even if the funktion ist ok) to recognize writing errors.
Your idea to use virtual pin assigments has maybe to much effort. If I understand correctly I would need to do that for all signals.
This are some hundred.
