The following error occurs when I run timing analysis:
"FATAL_ERROR:Timing:bastwoffsetpref.c:646:1.146 - Clock arrival time not found for client/CLIENT_A_RXCLK_DCM/CLKIN. Process will terminate. For more information on this error, please consult the Answers Database or open a WebCase with this project attached at http://www.xilinx.com/support."
This issue was resolved in ISE 9.2i sp1.
