请问下大家，最近在跑ICC的流程，我在创建power straps时，用的命令是
create_power_straps -direction vertical \
                  -configure step_and_stop \
                  -nets {VDD VSS} \
                  -layer METAL4 \
                  -width 1.5 \
                  -start_at 15 -step 30 -stop ${core_urx} -pitch_within_group 1.8 \
                  -ignore_parallel_targets \
                  -keep_floating_wire_pieces
然后出现了好多blockage的警告，Warning: wire dropped because obstruction, ((196.250 4.975) (197.670 5.255)) (Net: VSS) (Layer: METAL3 [28]) is blocked by ((3.500 3.500) (246.180 5.000)) (Net: VDD) (Layer: METAL3 [28]). (PGRT-030)
Warning: wire dropped because obstruction, ((224.375 244.045) (225.625 245.295)) (Net: VDD) (Layer: METAL3 [28]) is blocked by ((224.375 243.850) (225.625 244.390)) (Net: VDD) (Layer: METAL3 [28]). (PGRT-030)
Warning: wire dropped because obstruction, ((226.250 4.975) (227.670 5.255)) (Net: VSS) (Layer: METAL3 [28]) is blocked by ((3.500 3.500) (246.180 5.000)) (Net: VDD) (Layer: METAL3 [28]). (PGRT-030)
类似这样的警告，请问下这样该怎么处理呢
