Honored ContributorNo, you have to use an attribute to populate the ram with a .mif/.hex:

You will need to read in the text file and parse it manually. If you use a ram from the megafunctions library, you can specify the .mif as a generic and this block will parse the file for you, populating the contents in both simulation and synthesis.
