Labview FPGA 编译错误 - Unspecified I/O Standard

[johnsnow34]

编译一个VI文件时出现以下报错：

ERROR: [DRC NSTD-1] Unspecified I/O Standard: 18 out of 192 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all I/O standards. This design will fail to generate a bitstream unless all logical ports have a user specified I/O standard value defined. To allow bitstream creation with unspecified I/O standard values (not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks NSTD-1].

报错信息说应该指定I/O标准，在labview里具体应该怎么操作呢？附件里为项目中fpga的I/O接口名，及VI文件。 运行环境：win10, Labview FPGA 2018, 编译工具Vivada 2017.
