Are there any problems with Adaptive Equalization (AEQ) in Stratix IV GX and GT devices?


Yes, a problem with the Adaptive Equalization IP on Stratix IV GX and GT devices in Quartus II Software Version 10.1-SP1 and earlier prevents the IP from converging on a final value. The IP will time out and the Adaptive Equalization IP will fail to finish.

This issue will be fixed in a future version of the Quartus II software.
