1.10.119. FITTER_AGGRESSIVE_ROUTABILITY_OPTIMIZATION

Specifies whether the Fitter aggressively optimizes for routability. Performing aggressive routability optimizations may decrease design speed, but may also reduce routing wire usage and routing time. The default setting of Automatically lets the fitter decide whether to perform these optimizations based on the routability and timing requirements of the design.
