Arria II GX TTK configuration problem running at 6Gbps

Thanks for quick reply. I am using Arria II GX 95 with I3 speed grade.

I don't understand the requirements for 6 Gbps operation and Transceiver toolkit interaction and specifically the custom_PHY.

I have a working design running at 6 Gbps (CPRI) already. The problem we are having is errors in the link. Looking at custom PHY and CPRI interface PHY, fields don't match either.

It feels like Arria-II GX is an orphan in terms of explaining the TTK operations.

I thought I would do the following changes to get it working with 6 Gbps.

1. Change FPGA Fabric to Transceiver with to 16 bits.

2. Enable 8B/10B encoder/decoder

3. Set word alignment pattern to K28.5(-?)

4. Set datapath to 16 bits.

I don't mind using any other PHY to test the performance @ 6 Gbps such as SATA but there is not much to go with Arria II GX. All examples are for 1-2 Gbps.

How did you configure the transceivers for SATA 3.0 on Arria GX II?
