Why the DFE can’t find the optimal parameters sometimes?


Quartus® II 10.0 SP1 sets incorrect parameters for the Decision Feedback Equalizer (DFE) circuitry that could adversely impact the link BER. You can install Quartus II 10.0 SP1 patch 1.144 and recompile your design to resolve this issue.  This patch sets the DFE parameters correctly during compilation. If your design uses the DFE feature.
