LogiCORE SPI-4.2 (POS-PHY L4) v7.4 - DPA Continuous dynamic alignment has issues with realignment


When I use the continuous dynamic alignment feature that was introduced in SPI-4.2 v7.4, I sometimes receive erroneous DIP4 errors.


The fix for this issue will be available in v7.4 patch, expected some time in April 2006. 

Until the patch is available, please do not use the continuous dynamic alignment feature. 


Also, using PMCD for sink core clocking option is not recommended unless continuous dynamic alignment is used . Please do not use PMCD for sink core clocking until the v7.4 patch is installed. The patch is available from (Xilinx Answer 23155).
