4.1. Physical Synthesis Optimizations

The Intel® Quartus® Prime Fitter places and routes the logic cells to ensure critical portions of logic are close together and use the fastest possible routing resources. However, routing delays are often a significant part of the typical critical path delay. Physical synthesis optimizations take into consideration placement information, routing delays, and timing information to determine the optimal placement. The Fitter then focuses timing-driven optimizations at those critical parts of the design. The tight integration of the synthesis and fitting processes is known as physical synthesis.

The following sections describe the physical synthesis optimizations available in the Intel® Quartus® Prime software, and how they can help improve performance and fitting for the selected device.
