Extraction Tech File and LEF-Tech Map file for power grid libray

biju4u90

What are Extraction Tech File and LEF-Tech Map file used for generating power grid library in Encounter Power System? Can I generate these files manually? Can anybody please provide sample Extraction Tech File and LEF-Tech Map files?

Thanks in advance

    i think there was a way to capture the lef map created internally, but i don't recall the instructions. if you search COS you might find it. at least that one is easy to create with the lef and ict files. the stream map is not created when you save GDS. it is an input that you need to provide. if you don't have a stream map in your PDK then hopefully you have the design rule manual for the process. there is usually a section that has the mask layers and datatypes.

    Hi Kari, 

    I am not sure to pull up a thread which was 4 years ago. I apologize in the case of inconvenience. I am using innovus and 65nm. I would like to know if the process is the same. I am very confused in finding the qrcTechFile as I can't find qrcTechfile for each corner separately. 

    Thanks in advance
