4.6. Report Register Spread

This option generates the Report Register Spread report, which enables you to identify registers with sinks that are pulling them in various directions. These registers may be potential candidates for duplication.

Registers that drive in opposite directions and connect to high fan-out can cause placement-warping effects on the floorplan, ultimately impacting fMAX. Therefore, this report allows you to pinpoint such registers across all projects within a group. Each row in the Merged Registers Spreads table organizes paths by bus name pattern, making it easier to identify similar paths that are common across all projects

When you select a row in the Merged Register Spreads table, the detailed information is displayed in the Register Spread details table. This table shows each path and its duplicates across all projects, along with the respective information for each path
