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.
