EMIF Toolkit create Memory Interface Connection problem

Hi all ,

I'm working on EMIF and i can't create connection with the EMIF tool kit to visualize the calibration report

i always get this error :

"Connection target /devices/1SG280HH(1S1|2S1|3S1)|..@1#3-11.4.1/(link)/JTAG/alt_sld_fab_0_alt_sld_fab_0_sldfabric.node_8/jtag_phy_0.jtag/master failed to execute the command. A response was not received from the connection target within the allowed time."
