Honored ContributorOpen drain pin assignment
Does anyone know how to make an output pin open drain? I made an open drain assignment to an output pin in the assignment editor, but Quartus ignores it.

Honored ContributorYou need to instantiate an open drain primitive just before the pin. For some reason Quartus wont do this for you when you use the assignment editor to make an open drain assignment.
