It works fine for me.

Why don't you explain what you have tried so far.

1) What are you trying to use the transceivers for?

2) How have you setup the IP core? Basic single/double-width mode, lane rates, number of channels, transmitter/receiver, etc.

3) Have you connected an ALTGX_RECONFIG block to it and are you clocking it correctly?

4) Have you created a reset controller that resets the ALTGX component according to the mode you are using it?

5) Have you written a Modelsim simulation to show that your design works in simulation?

Cheers,
