13.29.1.2 Run Place

Select this option to run the placer during Layout. By default, it reflects the current Layout state. If you have not run Layout before, Run Place is selected by default. If your design has already been placed but not routed, this box is cleared by default. You can also select the following incremental placement options.

• Incrementally: Select to use previous placement data as the initial placement for the next place run.
• Lock Existing Placement (fix): Select to preserve previous placement data during the next incremental placement run.

  Incremental options apply to the entire design. For more detailed control of the placer behavior (such as, to fix placement of a portion of the design), use the MultiView Navigator tools or set fixed attributes on the placed instances via PDC constraint files.
