Compiler

Compilation Speed



Specifies whether you want to increase compilation speed by up to 50% for designs that target ACEX® 1K, APEX 20K, APEX II, ARM®-based Excalibur, Cyclone, FLEX 10K®, Mercury, Stratix, or Stratix GX devices, using one of the following options:

Standard Fit

Specifies that you do not want to increase compilation speed for the design. Selecting this option preserves the fMAX for the design.

Fast Fit

Specifies that you want to increase compilation speed for a design by up to 50% by using the fast fit feature to increase the Fitter's compilation speed. Selecting this option may reduce the fMAX for the design.

Limit to one fitting attempt

If you specify a FLEX® 6000, MAX® 3000, or MAX 7000 device for compilation, the Compilation speed/fmax tradeoff option is dimmed to indicate that it is not available.
