Example Designs for UniPHY External Memory Interfaces May Not Compile for IP Cores from Earlier Versions

Description

The example design provided with version 10.1 may not compile with IP cores migrated from earlier versions of the Quartus II software.

Workaround/Fix

The workaround for this issue is to perform the following steps:

  1. In the Quartus II software, open the Settings dialog box on the Assignments menu.
  2. In the Category tree of the Settings dialog box, click Files to display the files list.
  3. Remove all the UniPHY files, including the .qip file and example project files,from the migrated project assignments.
  4. Add to the project the newly generated .qip file located in the <working_dir>/<variation_name>_example_design_fileset directory.
  5. Add to the project all of the files except for the memory model, from the directory <working_dir>/<variation_name>_example_design_fileset/example_project.
