Long Form Answer Record (LFAR): Eye Qualification with GT Debugger

Description

The IBERT core is designed for evaluating and monitoring the transceivers.

Eye Scan provides a picture of the serial signal error distribution.

  • How can I determine whether the quality of the signal is good or bad?
  • How can I judge from the eye scan if the signal has enough margin?

Solution

This Long Form Answer Record helps to build a new tool dedicated to automatic eye qualification, combining IBERT with GT_DEBUGGER (XAPP1322 and XAPP1295).

Note: igd_eyescan.tcl provided in this Answer Record is a new release of the eyescan. Please replace the old file in the gt_debugger directory.
