我请求一些帮助，因为我完全陷入了我的 VHDL 项目，包括在 Nios II 上实现笛卡尔到极坐标转换器。我所有的 VHD 文件都编译没有错误，但是当我想在 Modelsim 上模拟整个块时，这就是我得到的
# Loading work.counter(a)
# ** Failure: (vsim-3807) Types do not match between component and entity for port "rn".
# Time: 0 ps Iteration: 0 Instance: /bench_conversor/uut/compt File: C:/Users/Sandjiv/Desktop/test_VHDL/counter.vhd Line: 23
# ** Failure: (vsim-3807) Types do not match between component and entity for port "thetan".
# Time: 0 ps Iteration: 0 Instance: /bench_conversor/uut/compt File: C:/Users/Sandjiv/Desktop/test_VHDL/counter.vhd Line: 24
# Fatal error in file C:/Users/Sandjiv/Desktop/test_VHDL/counter.vhd
# while elaborating region: /bench_conversor/uut/compt
# Load interrupted
这应该很容易发现错误，但我检查了我的类型一千次，它们似乎都匹配。这里遵循计数器，转换器（整个块）及其工作台的代码。它们都再次编译，但我只在 Modelsim 上进行仿真时才得到这些错误。
