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 ContributorIn Quartus II assignment editor, you can set the pin as auto open drain.
You can also set it in *.qsf file: set_instance_assignment -name AUTO_OPEN_DRAIN_PINS ON -to XXXXX
