那是因为DDR中RAM需要的bmm elf文件没有吃进去，你可以参考example_top implement之后的impl_1目录下的脚本example_top.tcl.例如：
add_files -quiet /vivado_prj/ddr3_0_example.srcs/sources_1/ip/ddr3_0/ddr3_0.dcp
set_property netlist_only true [get_files /vivado_prj/ddr3_0_example.srcs/sources_1/ip/ddr3_0/ddr3_0.dcp]
add_files -quiet / vivado_prj/ddr3_0_example.runs/ila_ddrx_synth_1/ila_ddrx.dcp
add_files / vivado_prj/ ddr3_0_example.srcs/sources_1/ip/ddr3_0/sw/microblaze_mcs_ddr.bmm
set_property SCOPED_TO_REF ddr3_0 [get_files -all / vivado_prj/ ddr3_0_example.srcs/sources_1/ip/ddr3_0/sw/microblaze_mcs_ddr.bmm]
set_property SCOPED_TO_CELLS inst/u_ddr3_mem_intfc/u_ddr_cal_riu/mcs0[get_files -all / vivado_prj/ ddr3_0_example.srcs/sources_1/ip/ddr3_0/sw/microblaze_mcs_ddr.bmm]
add_files / vivado_prj/ ddr3_0_example.srcs/sources_1/ip/ddr3_0/sw/calibration_0/Debug/calibration_ddr.elf
set_prop
