Thank you for joining this Intel Community.
Based on my understanding, you are trying to access this wiki page : https://fpgawiki.intel.com/wiki/Running_DDR3_Memory_Test_with_NIOSII but unable to download the content.
If we are on same page, I am able to download the content by using Google Chrome engine. To make thing easier for you, I attached the downloaded files here for your review.
Hope this helps 😊
