Hi @ljking, first of all, thank you for your response!
I found a reference to 80-NK808-21 in LM80-P0436-35 Rev A. section 1.2, page 8.
The reference to 80-V9690-19 in LM80-P0436-35 Rev A. section 18.104.22.168, page 54.
And finally, I said I found the LM8-P0436-28 reference in the APQ8016 product specification, I made a mistake (I will edit my question), I found the reference in LM80-P0436-33 Rev B. section 1.1, page 6.
Thank you for telling how the S-model and IBIS files can be obtained!
And, about the link, I don’t know why is redirecting you to a zip file, is a link to the developer.qualcomm.com Snapdragon410E tools & resources page (I will edit this to, I posted as the Dragonboard410 tools & resources). Here a screen capture of the page that opens the link when I click on it:
I downloaded the hardware files from this page two weeks ago
And I think that this is all, sorry for missing the reference to the documents where I found the mentions to the missing files.
Thank you so much!!
