Synthesis Effort logic option Definition

A logic option that specifies the synthesis effort level. When set to Auto, Analysis & Synthesis completes all steps in the synthesis process. When set to Fast, some steps are omitted to accomplish synthesis more quickly; however, there may be some performance and resource cost.

Intel recommends setting this option to Fast only when running an early timing estimate. Running a "fast" synthesis produces a netlist that is slightly harder for the Fitter to route, thus making the overall fitting process slower, which negates any performance increases achieved as a result of the "fast" synthesis.

This option is available for all Intel devices supported by the Intel® Quartus® Prime software.
