Description
The DDR & DDR2 SDRAM Controller MegaCore function supports Stratix GX devices. However, when a DDR & DDR2 SDRAM Controller core is instantiated in an SOPC Builder system that targets the Stratix GX family you will receive an error message indicating the the DDR & DDR2 SDRAM Controller MegaCore does not support the Stratix GX family. You can workaround this issue by modifying the class.ptf file for the DDR & DDR2 SDRAM Controller MegaCore SOPC Builder component. To do this ensure that the SOPC Builder tool is closed then perform the following steps:
- Browse to the <DDR & DDR2 SDRAM Controller MegaCore install directory>/lib/sopc_builder/ddr_sdram_component folder and open the class.ptf file
- Inside the class.ptf file search for the following line:
Required_Device_Family = "STRATIXII,STRATIX,CYCLONEII,CYCLONE";
- Modify this line to read:
Required_Device_Family = "STRATIXII,STRATIX,STRATIXGX,CYCLONEII,CYCLONE";
Now, you can reopen the SOPC Builder tool and instantiate the DDR & DDR2 SDRAM Controller core.
