WebJan 12, 2024 · Intel FPGA使用Verilog语言编写的项目由多个v文件构成，分为三层: top层、uart层和idc层。现在问题是idc层的reg值无法反馈给uart层。请检查idc层中reg值的输出端口是否正确连接到uart层的输入端口。如果连接正确，可能需要检查uart层的读取代码是否正确。 WebJul 23, 2024 · Re: Verilog "output" vs "output wire". « Reply #2 on: July 22, 2024, 03:29:25 pm ». I believe the default in Verilog is to assign it wire type. Personally, I always explicitly declare a port as a wire or reg. SystemVerilog has a new type called logic which is automatically selects the proper type based on its usage in your module.
