Hi Ted Gao,

By referring to the lower layer code, I found that the ltssm is connecting to the test_out bus if the test out width is set to 9 bits. Probably, you can try to use the lower 5 bits of test_out bus.

assign test_out_test_out = { pcie_internal_hip_lane_act[3:0], pcie_internal_hip_dl_ltssm[4:0] };

Regards -SK
