CPRI 12Gb on Zynq-7000

How do I configure the LogiCORE CPRI IP to support 12Gb line rates on a Zynq-7000 FFG-3 device?

PG056 has stated since v8.6 that 12165.12Mb line rates are supported on -3 speed grades in FFG packages for Virtex-7, Kintex-7 and Zynq-7000 devices.

Sure enough, I have had no problems configuring for 12Gb on Kintex-7 FFG-3 parts.

However, when I try to configure the CPRI IP v8.10 using Vivado 2019.1 for a Zynq-7000 FFG-3 part, there is no option provided in the GUI for 12Gb. The maximum line rate available is 10137Mb.

Is the option for 12Gb supposed to be there? What might be preventing it from appearing?

Hi Rahul,

Thanks very much for your quick response.

Have I misunderstood the documentation, then? Or does the documentation need amending? In particular, the "Speed Grade Support" section of PG056 v8.10 chapter 2 says:

"12,165.12 Mb/s line rates are only supported on -3 speed grades in FFG packages for Virtex-7, Kintex-7 and Zynq-7000 devices. "

Cheers,

James
