New ContributorCyclone II Quartus Legacy Support
Please ignore post. One Intel download page only cites repositories that go back to 13.2, but this link brings you to a page that includes versions back to 2.2 -- Yikes!

New ContributorI'm the same boat as the original poster. I've registered and logged in, but still only see Quartus version13.1 and newer. is anyone else able to see and download the older versions?

I still see 13.0sp1 available for download:

Thanks ak6dn. I installed it and the first thing I noticed is lack of support for the SOPC build, which gets to the heart of my problem, which is core IP upgrades. I've already tried some earlier versions, to no avail. My issue is that the cores were generated by Quartus 7 (or 6, depending on whether I believe the output files or the SOPC builder opening dialog). I think this means I have to upgrade the cores starting with with either the last version of Quartus supporting the System Wizard or the earliest version supporting the SOPC builder (versions 6 and 7 which I was hoping to download and try). The main upgrade issue appears to be the DDR2 core. See below for an excerpt the generation report, ddr2_sdram.html).
All the generated files are present but I can't seem to get it to install using the SOPC builder. Qsys is even worse and omits all the cores during the upgrade. As a last resort, I suppose I can regenerate the library module with the "new component" option and add it back to the design, but I was hoping for an option that gets us closer to the original HDL as the verification and validation starting point.
Potentially complicating matters, judging from experimenting with different Quartus versions, there seems to be a point where the Quartus DDR2 core (I don't remember exactly but sometime between versions 10 and 12) where Quartus no longer supports Cyclone II, but before that Quartus version, this particular DDR2 core is not available. That's why I wanted to try version 7. Appreciate any further comments or suggestions.

I ran into a similar problem where a design I built in QSYS or System builder wouldn't compile. It was quite a while ago, so I'm not sure I remember all the details. I had to go in and "recompile" all the custom peripherals inside System Builder so that they were brought up to the same Quartus version. I use quotes around recompile bc I don't think that's the terminology that Quartus used. Again, this isn't exactly what you're seeing but perhaps it will send you in a useful direction.
