    edbapp = Edb(edbpath=targetfile, edbversion="2024.1")

    # adding design variable
    edbapp.add_design_variable("my_variable", "1mm")

    # parametrize trace width
    edbapp.modeler.parametrize_trace_width("A0_N")
    edbapp.modeler.parametrize_trace_width("A0_N_R")

    # adding project variable
    edbapp.add_project_variable("$my_project_variable", "3mm")
