You can use the Pin Migration View window to determine how specific pins in your design might migrate to a new Altera device. By viewing pin migration compatibility, you can view the pin gain or loss for each device and final pin functionality, as well as see pin connections to avoid having "no connect" pins. To view pin migration compatibility:

1. Create pin assignments.

2. On the Pin Planner View menu, click Pin Migration View.

3. To select a migration device, click Device and then click Migration Devices.

4. To show more pin information detail, right-click anywhere in the Pin Migration View window, point to Show Columns, and then click the pin information you want to display.

5. If you want to view only the pins that, in at least one migration device, have a different feature than the corresponding pin in the migration result, turn on Show migration differences.

   Note: Migration differences are generated only for the pin features in the displayed columns.

6. Click Pin Finder to open the Pin Finder dialog box and find and highlight pins with specific functionality.

7. If you want to view only the pins found and highlighted by the most recent query in the Pin Finder dialog box, turn on Show only highlighted pins.

8. To export the pin migration information to a Comma-Separated Value File (.csv), click Export.
