Hello,

I want to use QRC for extraction of a digital design. I saved .def file from soc encounter, and plan to extract rc. But I got such an error that it seems I can only use LEF or libgen.

But I think DEF should be fine for extraction. Is there anything wrong ?

Here is my command file. I lunched the qrc with "qrc -cmd qrc_cmd_file"

Any advice will be appreciated.

I know why. I need to specify the lef files in " input_db -type def -design_file xxx.def -lef_file_list <lef files> "

I would suggest to run it from inside encounter/innovus. it is way simpler, only takes 2 commands.
setExtractRCMode [options]
extractRC


look for the setExtractRCMode command, -engine option. this one defines if you are using native or QRC extraction. that is all.
