set_scan_signal site:edaboard.com

i have a netlist that have a scan_mode signal,but in the top level ,i didn't define a scan_enable signal.
how can i do in the DFT Compiler?can i choose a random as scan_enable signal
during DFT compiler?

set_test_signal scan_enable "your_design_scan_en"
search the doc for command reference .

set_scan_signal test_scan_enable -port [get_ports zio_sel]
zio_sel is a random function signal!
it works!
thank u

to create a new port u can use:
create_port -direction "in" {test_se}
set_scan_signal test_scan_enable -port test_se
