Description NO. currently in the Quartus® II software version 2.1 the Quartus II MegaWizard generated LPM_ROM file will call the library lpm. This is incorrect since the LPM_ROM file will instantiate an altsyncram which is defined in altera_mf.v
There are two workarounds:
1) Manually edit the file Change
LIBRARY lpm; USE lpm.lpm_components.all; to LIBRARY altera_mf; USE altera_mf.altera_mf_components.all;
2) Do not use LPM_ROM when targeting Stratix. Instead, please use altsyncram to instantiate all your memory.
This was fixed in the Quartus II software version 2.2.
