Hi, 

I will be back to travel on new project using Altera startix V. It is my first work on this area and i need your help. 

I try to implement the design example for Startix V GX on wikialtera for transceiver toolkit for four channel  

and it work perfectly. But when I try to change the VHDL code of generator or for checker and lets the loopback, I get always indication “Yellow—Test is running but no data is locked” that mean that the data send by the generator is lost. 

Any suggestion please. 

Thanks
