Comparing a CAM Netlist against an External Netlist |
|
Netlist comparison is the most efficient and reliable method of ensuring design integrity has been maintained during the manufacturing stages. This Guide assumes that you have already extracted a netlist, and you now want to compare it against an external netlist.
Note: The External Netlist file (from your CAD system) must be in standard format: IPC-D-356 or IPC-D-356/A
Note: One of the primary reasons you want to extract a netlist from your Gerber data is so that you can then do a comparison against a CAD-generated IPC-D-356 netlist.
Command Sequence
Import External Netlist
1. Select menu: File | Import | Netlist...
2. Select your CAD-generated IPC-D-356 netlist, and press OK.
3. Verify Netlist Format, and press Next.
4. Press Finish.
Note: The external netlist has now been imported into DFM Now!
Running Netlist Comparison
1. Select menu: Tools | Nets | Compare Nets...
2. DFM Now! will now perform an extensive netlist analysis.
3. Press button 'Finish' when done.
4. If any errors have been detected, DFM Now! will display the View Compare Net Errors
Note: The Compare Net Error Browser is an easy-to-use navigation tool used to locate and describe each detected error.
