With Coupling analysis, you can accurately understand signal integrity and optimize your design's performance. Coupling mode provides information about the 'aggressor'—the nearby geometry causing electromagnetic interference on the signal that you're analyzing. It gives the signal name of the conductive object and its layer. To identify parts of your design that need refinement, refer to the Coupling Results Tree.
The warm-to-cool gradient represents Coupling. In this context, the heat gradient serves as a guide for analysis: the warmer the color, the higher the coupling.
