Tere is error when creat Traffic Generator Connection

Hi all,

I face one problem, when I use EMIF debug toolkit to test DDR4 board which is build by myself, and I get one example design under customize the requirement of the DDR4 which I need when I generate the EMIF IP. I compiled this example, and downloading .sof file into fpga. I open the EMIF debug toolkit and can create Memory Interface Connection, I can make sure that the calibration is completed and successful and can re-calibrate the IP through downloading the intruction through the EMIF DEBUG TOOLKIT to the IP. But when I creat Traffic Generator Connection, there is always one error that blocks me to do next operation.

About the information: I enable " Add EMIF Debug Interface" and select " Use configurable Avalon traffic generator 2.0" & Export Traffic Generator 2.0 configuration interface.

　So about my problem, could one give me some advice?

Brs,
