Hi,


It is possible but I wouldn't recommend as you would be under utilize the transceiver throughput as it the Cyclone V GT can performed better compare to Cyclone V GX.


The device you are using is that the GT is able to run better compare to the GX device but it will be limited by the bitstream.

Hi,

thanks feedback. that means if I use complied bitstream target for 5CGXFC7C7F27C8 in 5CGTFD7C5F27C7. the function is fine. the only issue is that dnot utilize serdes performance of GT device (up to 6Gbps), right? if so, it is fine for my application. thanks.
