用zedboard设计了一个模块,创建工程时没有选板子,而是用的器件。把官方约束文件里和我用到管脚相关的放在我的约束文件里。综合后有警告:
[Common 17-55] 'set_property' expects at least one object. [/home/work/fpga/exer/zed_sw_led/zed_sw_led.srcs/constrs_1/new/zed_sw_led.xdc:143]
Resolution: If [get_<value>] was used to populate the object, check to make sure this command returns at least one valid object.
这一行对应的约束是:
set_property IOSTANDARD LVCMOS33 [get_ports -of_objects [get_iobanks 13]];
所以问题是找不到bank 13?这个错能出在哪里? |
