    Ubuntu on Mac, yay :) 

    Now I have Ubuntu 10.04 Lucyd Lynx running on my Mac, and I can compile VHDL with GHDL and also use GTKWave. Yay! 🙂

    Thanks to VirtualBox and the one who recommends it 🙂

    Half-adder in VHDL 

    Yay. My first code in VHDL.

    library ieee;
    use ieee.std_logic_1164.all;

    entity ha_CG is
    Port ( X : in std_logic;
    Y : in std_logic;
    Sum : out std_logic;
    Carry : out std_logic);
    end ha_CG;

    architecture Behavioral of ha_CG is
    Sum <= X xor Y;
    Carry <= X and Y;
    end Behavioral;

    Happy enough to successfully compile it with GHDL and Wine.

    GHDL is a compiler. It does not generate netlist. 

    Like has been said here:

    Unlike some other simulators, GHDL is a compiler: it directly translates a VHDL file to machine code, using the GCC back-end and without using an intermediary language such as C or C++. Therefore, the compiled code should be faster and the analysis time should be shorter than with a compiler using an intermediary language.

    Compiling VHDL with GHDL on Mac OS 

    1. Download GHDL for Mac OS download here
    2. Put the whole directory in the home directory
    3. Type a simple .vhdl code from here

      -- Hello world program.
      use std.textio.all; -- Imports the standard textio package.

      -- Defines a design entity, without any ports.
      entity hello_world is
      end hello_world;

      architecture behaviour of hello_world is
      variable l : line;
      write (l, String'("Hello world!"));
      writeline (output, l);
      end process;
      end behaviour;

    4. Compile the file:  wine ghdl.exe -a hello_world.vhdl
    5. Build an executable file:  wine ghdl.exe -e hello_world
    6. Run the code:  wine ghdl.exe -r hello_world or wine ./hello_world


    the working directory is : /Users/chika/.wine/drive_c/Program Files/Ghdl/bin

      When I write VHDL or Verilog I like to use automated tools. C-to-Verilog.com is a website which allows you to compiler your C code into hardware circuits. It has a great pipelining algorithm for superb performance.

      Thanks for this help on how to install and use ghdl in OS X unfortunately it does not work. Instructions seem not to cover what to do with the wine stuff. Could you please help?

      Hello! thanks for you instruction. However, wen i run a command line “wine ghdl.exe -a file.vhdl” it said that “-bash: wine: command not found”. so do i need to install wine? or just copy from the dmg that you provided? thanks!

        yes you have to install wine! 🙂

    Installing Wine on Mac OS 

    I have to install Wine, because I want to use GHDL to compile VHDL.

    Useful links:

    1. http://davidbaumgold.com/tutorials/wine-mac/
    2. http://wiki.winehq.org/MacOSX
    3. http://wiki.winehq.org/MacOSX/Installing

    But before installing Wine I had to installed Macports for Snow Leopard, downloaded from here.
