Select this option to enable the fitter to use pin feedback, whenever possible, when local macrocell feedback is not being used. The pin feedback path takes less time than the global feedback path. The fitter uses the pin feedback path instead of the global feedback path for output pin signals that do not have 3-state control or Slow slew rate. By default, this option is on in the Balanced, Speed and User-customized templates, and off in the Density template.
Note: This option is available only in the XC9500 family.
