Are there any issues with using the UniPHY EMIF toolkit with SOPC builder projects?


  • Quartus® II Subscription Edition
  • DDR3 SDRAM Controller with UniPHY Intel® FPGA IP

    Yes, for Intel® Quartus® II software versions 11.1 and later, the UniPHY EMIF toolkit is incompatible with SOPC builder projects. This is due to a change in the debug architecture.


    If you require to use the UniPHY EMIF toolkit and have an SOPC builder project in Intel® Quartus® II 11.1 or later,  some options are:

    1.  Convert the project to use Qsys instead of SOPC builder
    2. As a starting point, debug the External Memory Interface using the standalone example design project that can be generated with the UniPHY IP using the Megawizard flow.
    3. Not recommended, but you could generate the SOPC builder project in an earlier Intel® Quartus® II release than 11.1 and use the EMIF toolkit for that Quartus® II software version.
