IBIS-AMI files for Xilinx Kintex7

[soheyl]

I want to simulate GTX buses of Xilinx Kintex7 in Cadance Allegro PCB SI tools; but I need IBIS-AMi files for it. Do you know from where I can find them for Kintex7 devices and is there any difference between using IBIS-AMI files and IBIS files in Allegro?

Thanks

Try Xilinx first...
Though most FPGA software will export an IBIS file complete with the drive currents you have set for your ports.

On Xilinx website just IBIS files exists and these are not for GTXs.

I had the same problem with spartan6. then I had to contact Xilinx support, then they gave me the AMI models.
Normal ibis model and AMI model are totally different, they are not combined into one file.

As I said most FPGA compilers will spit out an IBIS file, try that, I have used these in preference to the generic files as the IO is preconfigured to the drive strength and pull up/downs catered for where applicable.
