I was looking at Lesson 6 of the High Speed Layout course, and about 50 minutes into the course Robert explains that if you download the Allegro Free Physical Viewer
you can download and look at memory model layout examples from the Jedec site. I had no trouble downloading the Allegro viewer, but I have no idea how to find
the memory model examples to download in their search form. Nothing seems to work.

Say I wanted to find the document used as the example for fly-by topology DDR3 memory Robert was looking at.

How would I find that or other examples on the Jedec site?

Thanks for your help.

Yes, they are not easy to find. Even I have to always spend some time to find the designs. Try this: Go on the JEDEC website (https://www.jedec.org/) -> Use the TOP RIGHT corner search and look for "Design Files":
