GHDL on mac m1
I downloaded https://github.com/ghdl/ghdl/releases/download/v3.0.0/ghdl-macos-11-mcode.tgz and extracted it to home directory ~.

If someone is good at programming languages like C, will they be good at description languages like VHDL?
Also, VHDL has its roots in Ada, not Pascal. (In fact, the ghdl simulation tool is written in Ada.)

What is the netlist file format?
If the goal is simulation, the output of the process is something that can be processed by a standard compiler (like gcc or llvm) or executed by a pseudocode interpreter. See, for example, what is done by ghdl.

Converting VHDL to Verilog using GHDL
Maybe you could try to minimize your example to a MWE (minimum working example that demonstrates the issue) and then do a bug report against GHDL at https://github.com/ghdl/ghdl/issues
Try a question here: https://github.com/ghdl/ghdl/issues . I have only used GHDL for VHDL, and it worked well for what I was doing with it, but the creator/chief maintainer(?) (Tristan Gingold) should be able to set your issue straight in a short while, and he is pretty active on github.

ghdl, how to include math_real?
replying to myself: I just installed this nightly on a Win10 box and it seems to "work" based on minimal tests. Note that you need to install MinGW.

Converting VHDL to Verilog using GHDL
I am not sure if this helps, but here is a project that also uses GHDL to convert a quite large VHDL setup (including package files) to Verilog: https://github.com/stnolting/neorv32-verilog
- Convert VHDL to Verilog using GHDL (using a RISC-V core as example)
- Show HN: Convert VHDL to Verilog using GHDL (+ first evaluation)
