i have made filter code in system generator then generate vhd for the

when i am running this vhd code in ISE and synthesis, i am receiving
this warning..
how can i remove this warning?

Number of bonded IOBs: 9458 out of 640 1477% (*)

This suggests too many inputs and/or outputs being used, if 640 is the limit.

However you are using the other categories within limits.

Are all your I/O lines listed separately, making them tally 9458?
Could it be that you will reduce the count by grouping associated I/O lines under a shared node?
A syntax problem?
Etc.
