Hi, I wrote the following constraint.sdc for gcd example (nangate45):
create_clock [get_ports clk] -name core_clock -period 2 #set output delay for all set_output_delay -clock core_clock -max 1 [all_outputs] set_output_delay -clock core_clock -min 0 [all_outputs] #except for one... unset_output_delay [get_ports resp_val] set_output_delay -clock core_clock -max 0.5 [get_ports resp_val] set_output_delay -clock core_clock -min 0 [get_ports resp_val]
When running opensta, I receive the following error : ... Error: unset_output_delay requires two positional arguments. number instances in verilog is 272 ...
I also tried (even though it is marked as optional in the manual)
unset_output_delay -clock core_clock [get_ports resp_val]
but same response. What am i missing ? Thanks, Quentin
You aren't missing anything; it is a bug. Fixed in 17eced5f unset_input_delay/unset_output_delay no delay arg
note that you can also use [delete_from_list [all_ports] [get_ports resp_val]]
ok thank you !
