ACT, MX, and DX Layout Options

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 is more precise and typically results in higher performance. This option is available only when timing constraints have been defined.

When not checked, Designer runs standard layout. Standard layout maximizes the average performance for all paths. Each part of a design is treated equally for performance optimization. Standard layout uses net weighting (or criticality) to influence the results. Delay constraints that have been set for a design during place-and-route are not considered, however a delay report based on delay constraints entered in Timer can still be generated for the design. This is helpful to determine if Timing-Driven Layout is required.

Place Incrementally
