Keywords: latency
Using ISE software 11.3 and the Distributed Memory Core v4.2, if you choose to register the output and set the Pipeline Stages option to 1, this is reset back to 0 when the core is generated and the following warnings are issued in the coregen GUI:
WARNING:sim:356 - The parameter 'Pipeline_Stages' is disabled, its value will default from '1' to '0'.
WARNING:sim:192 - Xco Parameter changed from (Pipeline_Stages,1) to (Pipeline_Stages,0) during Recustomization
How can I resolve this issue?

This issue will be solved in the 11.4 release of ISE. For now a tactical patch has been created to solve this issue. Please read the readme file included in the patch download before installing.ftp://ftp.xilinx.com/pub/applications/misc/ar33736_33737_dist_mem_gen_v4_2_rev1.zip
