IP Product: DDR3 SDRAM Controller MegaCore supporting UniPHY

Why do I see the error message in the MegaWizard when I try to generate UniPHY based DDR3 SDRAM controller for Stratix V device?


You may see following error message in the MegaWizard® IP generation window in Quartus® II software version 11.1 on Linux when you try to generate UniPHY based DDR3 SDRAM Controller IP for Stratix® V device. 

Error: couldn't open "altera_mem_if_ddr3_phy_001_sequencer_rom.hex": no such file or directory


The workaround is to always install Cyclone IV GX, even if it\'s not being used.

This issue is scheduled to be fixed in a future release of the Quartus II software.
