Description
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
Resolution
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.
