2.9. Design Floorplan Placement Guidelines

The following guidelines are key to creating a good design floorplan:
  • Capture correct resources in each region.
  • Use good region placement to maintain design performance compared to flat compilation.

A common misconception is that creating a floorplan enhances timing performance, as compared to a flat compilation with no location assignments. The Fitter does not usually require guidance to get optimal results for a full design.

Floorplan assignments can help maintain good performance when designs change incrementally. However, poor placement assignments in an incremental compilation can often adversely affect performance results, as compared to a flat compilation, because the assignments limit the options for the Fitter. Investing time to find good region placement is required to match the performance of a full flat compilation.
