Remaps the design to improve the critical paths in timing-driven mode by performing re-synthesis to reduce the depth of logic. This timing-based approach will replicate LUTs with fanout and collapse smaller LUTs into bigger functions at the expense of longer optimization runtime.
Note: LUTs with BEL constraints will still be optimized by Resynth Remap. To prevent optimization on LUTs with BEL constraints, add a DONT_TOUCH property with value TRUE to the LUT.
