There is an apparent bug with Xilinx ISE/EDK version 12 that shows itself when you try to build a project in ISE that has an EDK sub-project. The Synthesis step completes but the Implementation step fails. This article describes the problem and the solution.



THE ERROR

  • One instance of: “ERROR:NgdBuild:989 - Failed to process BMM information edkBmmFile.bmm”
  • Followed by many instances of: “NgdBuild:604 - logical block '[block_name]' with type '[block_name]_wrapper' could not be resolved. A pin name misspelling can cause this, a missing edif or ngc file, case mismatch between the block name and the edif or ngc file name, or the misspelling of a type name. Symbol '[block_name]_wrapper' is not supported in target 'virtex4'.” (one for each block in your design)


THE SOLUTION

  1. In ISE right click on "Implement Design" in the Processes Pane
  2. click on the "+..." icon to the right of the "Macro Search Path" field
  3. select the "/implementation folder in your edk project folder
  4. click "Ok"
  5. Rerun your ISE Build process
