How to extract all device properties from LVS rule file?

Version 2

    I would like to write a simple program to check if every device property has a mapping "trace property" command. I know I can get all "trace property" information from LVS report file, but how to get all device's property? Does anyone have script or know how to extract the properties of every device from LVS rule file?


    ps. Some property calculation is written in MACRO, and some is device's default setting...
