11 years ago --- Quote Start --- If you like the gui approach you can use the Pin Planner after the design is complete. Just compile the design with no pin assignments, then use the Pin Planner afterward to go in and edit the assignments that Quartus picked. At least I think that should work --- Quote End --- Yes, it should work in that way. And personally I prefer this way. Because it provides information about direction of pin, bank and especially voltage level. This helps to ensure we select correct voltage level for pin based on actual pin voltage from schematic. And this also helps to cross verify that PCB designer have routed signal to correct bank ( to be specific, incoming signal's voltage level meets voltage level in which it has been routed and same for outgoing signal). In past, I was used to use assignment editor. And I was only assigning pin locations. During one project, I got schematic at early stage of board design and I did same thing. But later on we came to know that one 3.3V level incoming signal was routed to bank having lower voltage level(1.8v). So that board needed to be revised. If I would had checked voltage level at earlier stage, its revision could have been avoided. Hope sharing this would help others to avoid similar mistake. Warm Regards, Bhaumik
