Hi all,
I am looking for the download link of the Altera DDR2 Sample Design 
named emi_ddr2_ciii.zip

It is supposed to contain a sample DDR2 interface design files for 
cyclone 3/4 devices.
I was unable to find this zip file anywhere in Altera sites or other 

The link altera provided for download is 

but it doesnt have the specified sample.

It would be very thankful if anybody has this file

After some hectic search, i could find the link as below

but the design is strictly for Cyclone 3. My device is Cyclone 4 gx.
I think there is no sample design available for DDR2 interface on 
Cyclone 4 gx.

Cyclone 3 and 4 are essentially the same silicon with different version 
numbers. Check the datasheets, chances are that the DDR interface is

 Thanks for the info.. I will try in that direction,
The added difficulty is that in current Quartus ii 14.0 synth tool, 
Cyclone 3 support is not provided. Cyclone 4 is only available. So i 
couldnt migrate and check the sample design in above link also. It 
throws some errors regarding license.
