Is there any way to pre-load the Altera DDR3 (Uniphy) Memory Model?

Hi - to speed simulation, I'd like to pre-load the memory with data. There is surprisingly little documentation that I can find on the Altera Memory Model. Can anyone point me in the right directio...

On-chip or off-chip memory?

On-chip memory can be initialised using a .mif or .hex file, specified when you create the memory in the MegaWizard Plug-In Manager. These files can be used both in the FPGA and for simulation. However, ModelSim expects these files to be located in a particular location which is different to the default location you're likely to chose when creating the memory.

Off-chip memory can be initialised but will have to be done in whatever rtl model you're using.
