13.7.2.6. Viewing Diagrams in the Eye Viewer

Some of the tables displayed in the toolkit can be viewed in a graphical format.

The following tabs and reports can be displayed:

  • Calibration report: Report types are DQ, DQS, or DM/DBI, and split between input and output delays.
  • Vref margining: Report types are Per-DQ, Merged for each DQS group, or Merged (an average across all the DQ margins), and split between input and output margins.
  • Driver margining: Reports either input or output margins on each DQ pin.

    To view these reports, follow these steps:

  1. Select Tools > Eye Viewer.
  2. Select the desired toolkit instance.
  3. In the Parameters section, select the desired tab from the drop-down menu.
  4. Click the Start button at the bottom right, to draw the report based on the selected parameters. (The following diagrams demonstrate how different reports may look, and are taken from various designs.)
