yes i generated another one with same connection of example ,but i've figure out problem cause :

we must set test_in[5] = 0;

to allow pcie enter compliance mode

the another issue now that Ltssm stall at Polling.Compliance(3) state !!

i doubt that the cause of this problem from either "reconfig_xcvr_clk" as it set to 125MHz and have timeQuest -ve slack or "I\O pin standard" as it silghtly different from rerferance manul of kit

thanks,
