How to create "extracted netlist file"

Hi All

I am trying to update the binding in the layout view with LVS results, in order to make the view Layout-XL compliant.

When reading the Cadence document, 2 files (.ixf and .net files) are needed as mentioned below.

"Note: PVS creates a .ixf cross-reference file in the svdb directory of the PVS run directory when using the PVS Create QRC Input Data option.

Note: PVS creates a .net extracted netlist file in the svdb directory of the PVS run directory when using the PVS Create QRC Input Data option."

For the .ixf file, it has been generated when I run the LVS and enable the “Create Quantus QRC Input Data”
 

But there is no .net file as mentioned by the document.

On the other hand, it has also been mentioned in the document
 

"If you run PVS in LVS mode with the -qrc_data argument specified, the extracted netlist gets created in the form of a .spi file in the same directory as the .ixf. The .spi file provides a normalized output for QRC and may not be useful for generating the binding file required by Update Binding. Therefore, you must ensure that you set lvs_keep_data to yes in your lvs.pvl rule file so that the extracted netlist output file is a .net file, which can be read by the Update Binding form."

But I did not find the “lvs_keep_data” in the lvs.pvl file.

Does any one have a clue how to get the "extracted netlist file", or has a work around to update the binding according to the LVS results.

Best Regards
