2.2 Debugging: Advance Dataflow The Advanced Dataflow debugging tool allows users to explore the connectivity of their design and trace different events during simulation. There are three display modes to help trace events propagating through the entire project: Hierarchical, Flat, and Gray. Learn how to enable settings to generate data for the Advanced Dataflow window, how to add/view modules in the Advanced Dataflow window, how to utilize context menus within the window (expand net to readers, expand net to drivers, etc.), and how to switch display modes.
