13.29.5.1 Timing-Driven

Select this option to run Timing-Driven Layout. The primary goal of timing-Driven layout is to meet timing constraints, with a secondary goal of producing high performance for the rest of the design. Timing-Driven Layout delivers performance that is superior to Standard Layout; Timing-Driven Layout is selected by default.

Layout is run in Standard mode when the Timing-Driven check box is cleared. The goal of Standard Layout is to optimize for routability.
