    Liberty File Usage in Addition to STA

    Hi all,

    I'm involved in the characterization of Liberty files and I was wondering what are the applications to them outside of STA?
    I'm wondering if they are used in Synthesis, possibly using the cell information from PnR. I also understand for Hierarchical Timing Analysis, the Extracted Timing Model is in the form of liberty files.

    Is there any where else in the design flow where the Liberty files are used?

    Synthesis makes heavily use of STA, thus uses liberty files a lot.
