IP core implementation of multiplier on FPGA Spartan 3e

Can you describe the multiplier? (Width, anything special about it, does it use the multiplication operator)

Is it using the embedded h/w multipliers in the s3e? What's the exact error message?

use the multiplication operator)

message?

I used the ip core of multiplier which is available in xilinx 12.2,then in the next step i assigned pins in the plan ahead.after that when i synthesised it gave these warnings: WARNING:Xst:647 - Input is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. WARNING:Xst:647 - Input is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. WARNING:Xst:647 - Input is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. WARNING:Xst:1306 - Output is never assigned. , Basically i wanted to learn how to implement an ip core on fpga kit, i will be very thankful for any kind of help! thanks.
