Hi,
Refer to page 37 (The example is given for unregistered output).
http://hamblen.ece.gatech.edu/up3/ug_ram.pdf You can generate a sample simulation waveform and launch the Quartus II Help for the lpm_ram_dp megafunction by selecting the Generate Sample Waveforms.
or
Quartus II Megafunction Reference options from the Documentation button.
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
