Hi All,

 

I am studying DDR simualtion by following the App note 10858, 'Performing Pre-layout DDRx Analysis in HyperLynx'.  The problem happened after I finished step 2.2, I created the boardsim file correctly, but the DQS/DQS# pins were twisted after I run the HypEdit.bat in command line. So I will get a warning message when I tried to run the DDRx wizard.

What should I do to change them to be correct? Thank you.

I attached this app note and the warnings I got for your convenience.
