[Stratix V] Capturing Eye Scan on Multiple Channels using tcl script

Hi,

I'm trying to capture an eye scan using the EyeQ block from the Transceiver Reconfiguration controller. I have written a script and it works for logical channel 0. When I try to use the same script and capture an eye on a different channel, it does not seem to work. I have modified the code to adjust the location of the different pattern checker and to set the logical channel address for the PMA block and the EyeQ block. Does anyone have any suggestions on how to figure out why it isn't working? I am able to capture an eye using the TTK on both channels (I'm just trying to get away from using the TTK), therefore, I know my hardware set up is correct. I think there must be some register I need to set that I just don't know about it.

In my Qsys block the reconfiguration controller is at address 0x800. The data pattern checker 1 is at 0xaa0.

Thanks!

    There was nothing wrong with my tcl script. The issue was with how the signal was being capture in tcl vs the ttk.
