For those of you who use IPC-D-356x format netlist in your board testers, I have two types of questions I am having trouble understanding:

Does anyone know if there is a difference in the quality of the data between IPC-D-356 and IPC-D-356A versions? Does the newer versions give any MORE data? IS a netlist a netlist or is there more to the story?

And when you load the IPC netlist into the tester you are testing the gerber-data-generated-board against the PCB-database-generated-netlist data. Since this happens at the back end, are you also comparing the IPC netlist to a gerber extracted netlist at the front end CAM? Are there potential problems with this comparison?
