Due to the width of high bandwidth buses, their placement can have an impact on routing congestion, timing, and power. A dataflow analysis facilitates inspection of the movement of data on high bandwidth buses by simplifying the netlist to enable easy navigation while preserving key placement anchor points.

When a dataflow design is created, a stripped down netlist is generated from the original full design netlist and it is displayed in the dataflow viewer. The dataflow netlist preserves bus nets above a user specified width and trims out bus nets below this threshold, scalar nets and lower level cells.
