Hi Sir, 

Do you please can help me for the question? There is a problem about compiler in dsp builder. I test a simple project with dsp builder, like the attachment. The analyze is pass. But the Synthesis is error. The messages is  ========================================================= Internal Error: Sub-system: PDB, File: /quartus/db/pdb/pdb_archive.cpp, Line: 2851 ..................................................... Error: Error during compilation: Synthesis failed   ========================================================   Thank you

My dear what you are trying to do will never work.... 

Please read the dsp builder manual first, try some examples ... then move for your own design... and ask if you need :)
