I am trying to send data from the FPGA to the ethernet transeiver on
the Nu Horizons Spartan 3A DSP board.
There is an on-board Micrel KSZ8041NL transceiver, and Nu Horizons has
provided a wrapper (.bit file) to talk to the transceiver. I have
downloaded it to the board, but don't know how to use the wrapper as
there is not much documentation, besides just the bit file.

Can anyone help ?

..bit as wrapper?
you are mistaken

..bit files are pre made demos only so you can only use to try out the
factory demo
you cant use it own designs at all

and as Nu horizons is no longer an Xilinx disti, i bet you get nil
xilinx support from nu

32% of annual sales gone! Man is that a shocker for Nu Horizons.

So I wonder what the "new" direction is for Xilinx?

Thanks for your replies.
@ Antti: I think I shall look at the following opencores
implementation: http://www.opencores.org/project,ethernet_tri_mode.
Does anybody have any particular suggestions ?.
