To implement the retimer internal eye monitor function the user needs to load the Latte custom GUI shell. The steps are listed as follows:
Select file C:\Users\<User ID>\Documents\Texas Instruments\DS560Latte\projects\DS560_VP40\setup\customGUI.astx.
(Replace the <User ID> with proper Windows login ID.)
Once the customGUI is loaded the vertical eye histogram of the received data across 64 bins can be plotted in Latte, as shown in Figure 2-8. Data can be captured in a finite set of approximately 64k samples or continuously.
Under the controls tab, select the channel (valid range is 0 to 3).
Set Capture type to Continuous or Finite samples from the drop-down mode.
Click on Start Capture to get the vertical eye in the Plot Eye data tab.
