Version

Yosys 0.39+165

On which OS did this happen?

Linux

Reproduction Steps

Hello, when using Yosys to synthesize an rtl.v file, during the synthesis phase, the port clk[0] in the module15 is either unconnected or has no load. Yosys should ideally issue a corresponding warning for this situation. (There are a total of 6 such warning messages, with detailed explanations provided in the attachment.)

Yosys doesn't lint. Use verilator or something else if you need linting features. See #4705
