There are three ways of getting UltraRAM primitives, as follows:

Direct instantiation
Provides you the most control but is the hardest to perform.
XPM flow
Allows you to specify the type of RAM you want along with the behavior, but gives no access to the RTL.
Inference RAM
Is in the middle of the two, relatively easy, and gives more control to the user on how the RAM is created.
