macbook m1 iverilog

[wlz987]

in setting,
set the iverilog path: /opt/homebrew/bin/iverilog
but it said no install iverilog:

由于：Verilog仿真器Icarus未安装，安装iverilog（http://iverilog.icarus.com/）并重新尝试。

The code that searches for the iverilog binary is quite sophisticated. I don't think this code is not working properly. I rather suspect it is a Mac-specific "security feature" that prevents execution.

I am having the same problem. When running the application from the terminal, the following error trace is shown. Might be helpful. I am using macOS Sonoma 14.4.4.1 with icarus-verilog from homebrew package manager.
