A: How do I find the file that stores the pin assignment? It's not listed under my files in the project navigator but the pins I've assigned in Pin Planner stay from session to session so they must be stored somewhere. I'm making a serial data receiver on it and have given it a Data In pin.
I suspect this is an error in the pdf, rather than in Pin Planner but seing as I've never worked with Altera products before, I'm very confused. B While I will sometimes use the pin planner in the early stages of a design, I almost exclusively edit the qsf file directly when modifying pins, adding or removing VHDL files from the design, etc. To be completely safe, when making large changes particularly to optimization or compiler settings I will make sure Quartus is not running.
I've been working this way with Quartus since it came out, and have not had any problems. In particular, refer to the column indicating whether or not the pin is manually assigned, as any pins not specifically assigned to a location will change pretty much every time you recompile the chip which is sub-optimal if you've already made a PCB!

On the Assignments menu, click Pin Planner. The Pin Planner automatically lists all design nodes and displays a device view showing All Pins. The selected item s appear in the Report window and are highlighted in the device view. To perform early pin planning, follow these steps:. To filter design nodes for assignment, follow these steps:.
Right-click in the Customize Filter. C lick New. In the Filter list, specify filter conditions under Query. To create a custom group of nodes for assignment, select one or more nodes in the Groups or All Pins list, and then click Create Group.
To make an assignment to a device pad, follow these steps:. I n the Groups list, select the node or group you want to assign to a pad. Drag the node to the pad to which you want to assign it in graphical representation of the target device in Pad View window. To assign differential pin pairs, follow these steps:. I n the Groups list, select the node you want to assign to a differential pin location.
To view the corresponding negative pin for differential pin pairs, follow these steps:. If necessary, select the Differential Pair column and move it from the Available columns list to the Show these columns in this order list. Drag the node to the differential pin in the device view. Important: Make sure you connect the positive node to the positive pin on the device and the negative node to the negative pin on the device.
To create board trace model assignments, follow these steps:. You specify board trace parameters on the positive end of the differential pin pair and the specified parameters are applied to the corresponding value on the negative end of the differential pin pair. Board trace model assignments that are made directly to the negative end are ignored.
If you select a differential pin pair, you must select the positive pin. To display additional pin properties, r ight-click anywhere in the All Pins list, and then click Customize Columns. T o add a node to an existing assignment group, follow these steps:. To add members to a group you created, right-click the group name in the Groups list, and then click Add Members.
To delete members from a group you created, select the entire row in the Groups list, and then press Delete on the keyboard. To incrementally move an assignment, in the View menu click the corresponding Assign command.
Thanks to our community members who provide support during our down time or before we get to your questions. We appreciate you! Need Forum Guidance? Hi, I am a beginner. How can we do pin assignment according to device?? How to import file? Anyone please help me. Thank you. All forum topics Previous topic Next topic. If you're new to this I recommend you use the Pin Planner tool built into Quartus.
