  1. In the Settings dialog box, select Fitting under Compiler Settings. The Fitting page appears.

  2. Under Timing-driven compilation, turn on Optimize timing, and Optimize I/O cell register placement for timing, and make sure Normal compilation is selected in the list.

  3. Under Compilation speed, make sure Standard Fit is selected.
