What are the things to be verified in the PCB gerber files?

Here are four things to be verified in the PCB Gerber File:

1.Whether PCB and schematic are correct or not—to generate the IPC netlist file;

2.Whether the design parameters meet the production process requirements or not;

3.Whether the PCB manufacturing files  are complete and the PCB size is correct or not;

4.Whether the process edge, the location hole and fiducial mask  are added or not;
