2.5. Design Place and Route
By default, the Fitter selects appropriate resources, interconnection paths, and pin locations. If you assign logic to specific device resources, the Fitter attempts to match those requirements, and then fits and optimizes any remaining unconstrained design logic. If the Fitter cannot fit the design in the current target device, the Fitter terminates compilation and issues an error message.
The Intel® Quartus® Prime Pro Edition Fitter introduces a hybrid placement technique that combines analytical and annealing placement techniques. Analytical placement determines an initial mathematical starting placement. The annealing technique then fine-tunes logic block placement in high resource utilization scenarios.
