Transceiver link connection error

Honored Contributor II

Hello, I'm a beignner of Quartus II tools.  


Now I'm using a Stratix V and the transceiver toolkit function. 

But there was an error of transceiver links while I'm measuring BER. 

The error script in tcl command window was as follows,  


"error: alt_xcvr_reconfig_eye_viewer_set_vertical_step: null" 


The transceiver link suddenly stopped in a for loop (controlled by a tcl script) with the error. 

I couldn't figure out that reason of the error. 

Attached is the figure of the link status. 


Can anyone help me? 


Thank you 

Insun Shin
