Patch created on October 13 2010 Patch SPR#: 356399 SPRs fixed: 355076 //**************************************************************** Problem: The UniPHY QDRII IP core operating in full-rate mode can exhibit intermittent failure during calibration. The failure is caused by an unreliable asynchronous transfer going from the AFI clock domain to the read-capture clock domain. Solution: The patch fixes the issue by ensuring that the asynchronous signal can reliably be captured by the read-capture clock domain. This is done by ensuring that the asynchronous signal lasts for two read-capture clock cycles, and that there is no combinational logic in the cross-clock-domain path. Caution - You must either have previously installed the Quartus II 10.0 SP1 software or must install the Quartus II 10.0 SP1 software before installing this patch. Otherwise, the patch will not be installed correctly and the Quartus II software will not run properly.
