Hi @Blues-sptn​ 

 

In Assignment Editor, To: <pin name>

Assignment name: Output Delay Chain Setting or Input Delay chain setting

Value: <how much delay you want>

Enabled: Yes

set_instance_assignment -name OUTPUT_DELAY_CHAIN <value> -to <pin name>

set_instance_assignment -name INPUT_DELAY_CHAIN <value> -to <pin name>

 

Example:
