    Hi RichardTanSY_Intel

    Oh, I get it. Thank you, RichardTanSY_Intel, so much.

    Can I ask another question?

    You said that "specify the start and end point if want to check the delay between the specific LCELL."

    Could I use "report_path" command twice to report the delay into the same panel?

    Ex.

    (1)

    report_path -from [ get_pins {top|IP_1|Inp_dly1|dly1d|combout}] -to [ get_pins {top|IP_1|Inp_dly1|dly2d|data*}]

    -npaths 1000 -panel_name LCELLs_delay

    (2)

    report_path -from [ get_pins {top|IP_1|Inp_dly1|dly2d|combout}] -to [ get_pins {top|IP_1|Inp_dly1|dly3d|data*}]

    -npaths 1000 -panel_name LCELLs_delay

    There use "report_path" command twice.

    Could the second "report_path" command report the delay that append into the same "LCELLs_delay" panel, but not overwrite?

    Thank you very much.
