4.3.3. Physical Synthesis Effort Settings
If your design meets your performance requirements without physical synthesis options, turn them off to reduce compilation time. For example, if some or all the physical synthesis algorithm information messages display an improvement of 0 ps, turning off physical synthesis can reduce compilation time.
You also can use the Physical synthesis effort setting on the Advanced Fitter Settings dialog box to reduce the amount of extra compilation time used by these optimizations.
The Fast setting directs the Quartus® Prime software to use a lower level of physical synthesis optimization. Compared to the Normal physical synthesis effort level, using the Fast setting can cause a smaller increase in compilation time. However, the lower level of optimization can result in a smaller increase in design performance.
