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.
