High-bandwidth buses can affect routing congestion, timing, and power because of their width. Use dataflow analysis to inspect how data moves through these buses. This analysis simplifies the netlist to make navigation easier while preserving key placement anchor points.
When you create a dataflow design, the following applies:
- Vivado generates a simplified netlist from the full design netlist.
- The dataflow viewer displays this stripped-down netlist.
- The dataflow netlist keeps bus nets above a user-defined width.
- It removes bus nets below this threshold, scalar nets, and lower-level cells.
