Please,Anyone could help me in timing constraint error ?

[adam_lo]

Hello,
Please, I need help so much.
I don't now why when I add my custom ip core .this error appeared.
what this error mean?
and how to solve it ?

ERRORack:1653 - At least one timing constraint is impossible to meet because
component delays alone exceed the constraint. A timing constraint summary
below shows the failing constraints (preceded with an Asterisk (*)). Please
use the Timing Analyzer (GUI) or TRCE (command line) with the Mapped NCD and
PCF files to identify which constraints and paths are failing because of the
component delays alone. If the failing path(s) is mapped to Xilinx components
as expected, consider relaxing the constraint. If it is not mapped to
components as expected, re-evaluate your HDL and how synthesis is optimizing
the path. To allow the tools to bypass this error, set the environment
variable XIL_TIMING_ALLOW_IMPOSSIBLE to 1.


For more information about the Timing Analyzer, consult the Xilinx Timing
Analyzer Reference manual; for more information on TRCE, consult the Xilinx
Command Line Tools User Guide "TRACE" chapter.
INFO:Timing:3284 - This timing report was generated using estimated delay
information. For accurate numbers, please refer to the post Place and Route
timing report.
Asterisk (*) preceding a constraint indicates it was not met.
This may be due to a setup or hold violation.

Mapping completed.
See MAP report file "system_map.mrp" for details.
Problem encountered during the packing phase.

Please, Realy I need your help so..... much

thanks in advance

Go to timing report and see which path is getting failed and analyze the path delays...
