Remaps MUXF7, MUXF8, and MUXF9 primitives to LUT3 to improve routability. You can limit the scope of mux remapping by using the MUXF_REMAP cell property instead of the -muxf_remap option. Set the MUXF_REMAP property to TRUE on individual MUXF primitives.

Note: Not applicable to Versal.
Tip: To further optimize the netlist after the mux optimization is performed, combine the mux optimization with remap (opt_design -muxf_remap -remap).
