How to Set the Output Delay of the Arria 10 I/O

[Blues-sptn]

In the Transmit path setup/hold section on page 50 of the document below,

--

Arria 10 I/O can provide up to 800 ps additional delay on outputs. This delay is enabled using the output delay logic option within the assignment editor in Quartus Prime.

It says.

However, I don't know how to set it with assignment editor.

How do I set the assignment editor?

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

=====OR=====

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

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

Example:

set_instance_assignment -name OUTPUT_DELAY_CHAIN 4 -to pin_name1
