3.5.7. Location Assignments

If a small number of paths are failing to meet their timing requirements, you can use hard location assignments to optimize placement.

Location assignments are less flexible for the Intel® Quartus® Prime Fitter than Logic Lock (Standard) assignments. Additionally, if you are familiar with your design, you can enter location constraints in a way that produces better results.

Note: Improving fitting results, especially for larger devices, such as Arria® and Stratix® series devices, can be difficult. Location assignments do not always improve the performance of the design. In many cases, you cannot improve upon the results from the Fitter by making location assignments.
