Invert CLKOUT setting for DDR3 ratio seed

Intellectual 935 points

Hi all,

I am trying to get the ratio seed value for DDR3 by ratio seed excel file.

The invert CLKOUT setting follows as behind. If (DDR_CK length) < (DDR_DQS length), then use 1. If (DDR_CK length) > (DDR_DQS length), then use 0.

In my case, the DDR trace length as below:

Which invert CLKOUT setting(0 or 1) should I use?

Thanks.

Sherry
