recommended Quartus Prime version for Stratix IV




I'm working on upgrading an older design made for a Stratix IV FPGA with new features. For this I want to use the latest available Quartus Prime software supporting it. In both the Prime Standard Edition 20.1.1 and 21.1 I succeeded to upgrade the IP to the latest version coming with the design tools. The design includes a PCIe and DDR3 controller. Both are showing errors when trying to generate them in platform designer. The PCIe controller seems to need a ip_compiler library that is missing and the DDR3 core fails to generate and compile a sequencer executable.


So, what is the best software to use to design and route the Stratix IV GX family today ?


Best regards

Can you show the exact errors?  You should be able to upgrade those cores in the latest versions.  If not, you can just recreate them with the same parameters and that usually fixes issues.


The DDR3 core gives me these errors. I tried several different DDR3 presets. They all gave me this error:

The PCIe core creates these error messages:

Error: altgx_internal: error copying "C:/intelfpga/21.1/quartus/../ip/altera/ip_compiler_for_pci_express/lib/altpcie_serdes_4sgx_x8d_gen1_08p.v": no such file or directory

The second error I resolved by copying over the old IP_COMPILER libraries from an older version of Quartus.






Which OS are you using? If window, have you installed the WSL?

You need to install WSL followed by a Linux distribution for Nios Command Shell to work in Windows:


I think this is related to the KDB below, could you try to install the patch and see if it works.


May I know does my latest reply helps in your issue?




I'm sorry for the late answer. I followed your advice and some others I found and succeeded to route the FPGA now. Main trick was to install the Linux version on an Ubuntu box. In addition I needed to follow this advice to get the tool chain set up:


Thank you for your help


Best regards
