5.2.2.1. Guideline: Modify Pin Assignments or Choose a Larger Package

If a design that has pin assignments fails to fit, compile the design without the pin assignments to determine whether a fit is possible for the design in the specified device and package. You can use this approach if an Intel® Quartus® Prime error message indicates fitting problems due to pin assignments.

If the design fits when all pin assignments are ignored or when several pin assignments are ignored or moved, you might have to modify the pin assignments for the design or select a larger package.

If the design fails to fit because insufficient I/Os pins are available, a larger device package (which can be the same device density) that has more available user I/O pins can result in a successful fit.
