Determine whether you want to migrate your design to another device density to allow flexibility when your design nears completion. You may want to target a smaller (and less expensive) device and then move to a larger device if necessary to meet your design requirements. Other designers may prototype their design in a larger device to reduce optimization time and achieve timing closure more quickly, and then migrate to a smaller device after prototyping. If you want the flexibility to migrate your design, you must specify these migration options in the Intel® Quartus® Prime software at the beginning of your design cycle.
Selecting a migration device impacts pin placement because some pins may serve different functions in different device densities or package sizes. If you make pin assignments in the Intel® Quartus® Prime software, the Pin Migration View in the Pin Planner highlights pins that change function between your migration devices.
