10Gbps PCB design
« on: July 25, 2020, 02:42:35 am »
Hi

I am designing an RTM board for an ATCA crate. The rtm is for a Trigger Processor carrier board that has a couple 7 series Xilinx FPGA's with GTY transceivers that will be sending and receiving data through a fancy new EBTF samtec high density high speed zone3 connector. My RTM has 8 QSFP modules that will have a total of 31 channels that have to run 10Gbps. I am curious if there is anyone on the forum that has experience designing multi gigbit designs. Our first prototype was a flop and my BER is 10^-10 and 10^-9  |O |O |O when I run Xilinix's IBERT project using a PRBS31 but works some what at PRBS7.

Cheers

Sure, I have dabbled in high-speed baseband stuff. But it's kinda hard to say without knowing more info about what you are doing where the problem lies.

What is your design flow? Did you manage to simulate your connector landings? Maybe even fully simulate the connectors?
