Problem with DDR2 SDRAM Controller with Altmemphy

Question

Hi,

I have been working with Quartus 10.1sp1 web edition with cyclone III Development kit for 6 months now but some time ago the s/w stopped generating the .limited sof file if I used High Performance Arch II in the design which previously was working fine. It works only with HPC architecture in DDR2 SDRAM controller. I uninstalled and reinstalled many times but still the problem exsists.

Does anyone have the same problem? I dont understand why this problem occured.Does anyone know about it?

Thanks

Sn

What problem? The core doesn't generate .sof file at all or does generate, but not time limited?

Doesnt generate the.limited file.

So it doesn't generate any .sof file at all? Then check if You haven't disabled the .sof file generation if there ore time limited cores.

It modifies the .sof file but the same design which was worked before with .limited sof file doesnt work with .sof file.It is strange..Since I am using the free version it should create the .limited sof file which is not being generated

I am not sure, but after certain version of Quartus, the DDR2 controller hasn't been encoded to limited version, so now it is probably free, but You better create a SR concerning this question.
