6–130 Chapter 6: Fitter Assignments
FIT_ATTEMPTS_TO_SKIP
FIT_ATTEMPTS_TO_SKIP
Type
Controls how many fit attempts the Fitter skips. In subsequent fit attempts, the Fitter
uses higher effort to improve design routability at the expense of longer compilation
times. Use this setting to force the Fitter directly into a second or third fit attempt,
which will save time when it is known that multiple attempts are needed. This setting
causes the same amount of additional effort to be applied but does not guarantee an
identical result to what would be achieved if all fit attempts were performed. For
some families, the Fitter will not perform a third fit attempt automatically due to the
long compilation time and possible timing quality degradation. However, a third fit
attempt can still be forced to run by setting this value to 2.
