2.6.5.1. Intel® Quartus® Prime Software Option for Multiplexer Restructuring

Intel® Quartus® Prime Standard Edition integrated synthesis provides the Restructure Multiplexers logic option that extracts and optimizes buses of multiplexers during synthesis. The default Auto for this option setting uses the optimization whenever beneficial for your design. You can turn the option on or off specifically to have more control over use.

Even with this Intel® Quartus® Prime-specific option turned on, it is beneficial to understand how your coding style can be interpreted by your synthesis tool, and avoid the situations that can cause problems in your design.
