The UT_FauFTB is the python module of uFTB of XiangShan which can be imported in the testcases. For example, you can import the module by the following code when your python file is in the picker_out_uFTB directory.

from UT_FauFTB import *

if __name__ == "__main__":
    uFTB = DUTFauFTB()
    dut.init_clock("clk")

    # Your testcases here

    uFTB.finalize()

The other modules such as Tage_SC are similar to uFTB. You can import them in the same way.
