Guidelines to use Eye Viewer feature for Stratix 10 SoC Dev Kit

Hi, Any user-guide is available to plot eye-diagram using Eye Viewer option using Transceiver toolkit? I am using Stratix 10 SoC (L-tile) Dev kit with Quartus 18.1 Pro tool. With Regards, HPB

HI HPB,

For eye viewer test run time control :

  • Increasing the step interval to bigger value (like from 1 to 4) will reduce the test run time but at the cost of lossing measurement accuracy
  • Different adaptation mode shouldn't impact the test run time. It will just impact whether do you get optimized setting for SI performance or not

Sorry we don't have exact breakdown or decoding of eye width or eye height unit/interval. It's just relative measurement tool to help user tune different PMA setting to find out the biggest optimized eye diagram.

Thanks.
