When I have an OFFSET OUT constraint with the RISING or FALLING keywords, the following error occurs:
"FATAL_ERROR:Timing:bastwoffsetpref.c:679:1.160.14.3.10.1 - Clock arrival time
not found for your_clk. Process will terminate. For
technical support on this issue, please open a WebCase with this project
attached at http://www.xilinx.com/support."
How do I work around this issue?
This error can occur when MAP removes one of the clocks, or if the clock contains a TIG constraint. To work around this issue, remove the RISING and FALLING keywords.
This is a known issue and is scheduled to be fixed in the next major release of the software.
