Eye pattern using TCL script

[Altera_Forum]

Is there any way to generate an eye pattern using TCL sript. I'm a newbie here so i have no idea regarding how to do that.

Only then should you look into writing your own eye pattern Tcl code.  Read the Transceiver Toolkit documents I have written on this page:  https://www.ovro.caltech.edu/~dwh/correlator/cobra_docs.html  Cheers, Dave   Cheers, Dave

Thanks a lot Dave for your quick reply and valuable suggestions. Along with the documents which you have mentioned, can you suggest standard references which are helpful for me so that i can go through them simultaneously.

The FPGA handbook -> read the transceiver chapter  2. The Quartus Handbook -> read the Transceiver Toolkit chapter  3. The documents I provided -> they make more sense than 1+2 alone :)  Cheers, Dave

Hi, 

 Based on my experience, generally it is recommended to use the XCVR toolkit to plot the eye diagram with EyeQ feature. The XCVR toolkit will provide a user friendly GUI for easy interpretation. Note that XCVR toolkit can only plot eye diagram for single UI.

The TTK is completely broken in the latest versions of Quartus, so its far from user friendly :)  The TTK tutorial I linked to has a list of the bugs, eg., the TTK autodetects channels, but unless you have selected the hard-coded addresses someone at Altera coded into the GUI, it will not work. (This applies to v15.0 and some of the other latest editions of Quartus).  Cheers, Dave

Agree with Dave. I often encounter bugs ie autodetects channels especially when trying to customizing the toolkit design example from web or self created toolkit design. Most of the time, I am still using the design example from web with QII 13.1 - the closest version from the latest design example 13.0sp1 available.

Normally I will use the design example from web with QII 13.1 as well to avoid compatibility issue. Find the PMA optimal settings and then apply back to my actual design.

Hello Dave, 

 i have gone through the documents and simultaneously started working on it.i have come across auto sweep feature as well as EyeQ feature in toolkit. I want to automate the task of generating the auto sweep results in a table format (.csv file) using TCL. Is there any inbuilt TCL procedure in tool kit to generate and access the list of results.

I never had much luck with the autosweep. Perhaps you will fare better.   File a Service Request with Altera and ask them.  Cheers, Dave
