Hi ebrockhoff,

The solution was to use the "OUTPUT_ENABLE_GROUP" keyword. Easies way is to run a tcl script that corresponds to your hardware. For example, if you are using an Altera Dev Kit, there will be tcl script that will do this for you in the files/directories that are created after you install the software associated with your Altera Dev Kit. In summary:

1. tcl script files are the files that end in *.tcl

2. In Quartus II go to Tools | Tcl Scripts....

3. View the Tcl Scripts that correspond to your Altera Dev Kit hardware with DDR and use the "OUTPUT_ENABLE_GROUP" keyword.

By the way, you can also view and modify the tcl files with note pad or any other text editor if you want.

If this helped you in anyway please add to my rep.

Cheers,

Max
