如果bump的pin正确连接，用下面脚本抓：
foreach_in_coll obj [get_cells -filter "ref_name =~ BUMP*" ] {
    set j_bump_center_x [expr [lindex [get_attr $obj origin ] 0 ] + 44 ]
    set j_bump_center_y [expr [lindex [get_attr $obj origin ] 1 ] + 44 ]
    set j_pin_net_name [get_object_name [get_nets -of $obj ] ]
    puts "$j_pin_net_name $j_bump_center_x $j_bump_center_y"
}
