For designs synthesized with Vivado synthesis, it is possible to cross-probe back to the source files once the netlist design is in memory.
To cross-probe:
- Select the gate.
- Select Go to Source from the popup menu, shown in the following figure.
Figure 1. Cross-Probe Back To Source
Use cross-probing to determine which source is involved in netlist gates. Due to the nature of synthesis transforms, it is not possible to cross-probe back to source for every gate in the design.
