vivado下ERROR: [USF-XSim-62] [VRFC 10-3180]

ERROR: [USF-XSim-62] ‘elaborate’ step failed with error(s). Please check the Tcl console output or ‘C:/workplace/VIVADO/resize/resize.sim/sim_1/behav/xsim/elaborate.log’ file for more information.

elaborate.log内容：ERROR: [VRFC 10-3180] cannot find port ‘threshold’ on this module

原因：两个 IP生成了同样名字的xx.v，实例化这两个IP时xx.v都被拷贝到’C:/workplace/VIVADO/resize/resize.sim/sim_1/behav/xsim’下，先生成的被后生成的覆盖。导致先生成的IP提示有些port丢失。

这种小众开发环境真的挺傻的。
从ISE->vivado->vivadoHLS -> SDSOC/SDAccel->VITIS 。这些开发环境生命周期都不长，xilinx要反思！
