I am trying to get a Virtex 6 to communicate over a ribbon cable to a Spartan 6.
Am not getting Lane_Up or Channel_Up.
Implemented an IBERT project and was able to get zero errors by increasing the TXDIFFCTRL to 729mv on the Spartan 6 TX lines.
Everything is good except I have no idea how to use the TXDIFFCTRL value in my program.
Is it a special file, a ucf, a system environment?
One document for Virtex 5 indicated that I would be able to use the value from IBERT in the GTP settings of the Wizard but I was not able to find that in the Serial Connectivity Wizard.
After having used Serial Comunnications Aurora 8b/10b Coregen for several projects, they were always communicating to SFP modules.
To be able to modify transmitter and receiver settings, you have to use the GTP Wizard.
