4.3.2. Placement Effort Multiplier Settings

The Placement Effort Multiplier option controls how much time the Fitter spends in placement. Click Assignments > Settings > Compiler Settings > Advanced Settings (Fitter) and specify a value for Placement Effort Multiplier.

The default value is 1.0, and valid values are greater than 0. Specifying a floating-point number allows you to control the placement effort. A lower value decreases the CPU time but may reduce placement quality. You cannot directly increase the Placement Effort Multiplier to a value greater than 1.0. Use predefined Optimization Mode settings to increase placement effort for improved timing optimization.
