The OS X gtkwave.app is sensitive to two file types with extensions. This is a run command option along the lines of '-stop-time=587200ns'. VHDL will only stop executing when either ther are no more scheduled signal updates or execution time maxes out.

You should also limit the run time duration with a guard timer should your test bench provide a free running clock. Also see the vcd options in that directory should you choose to use VCD instead. There's a waveform format unique to ghdl called ghw, which can be invoked with the run command option '-wave=.ghw'. (You can select an application in the Applications folder and 'Show Package Contents' to navigate to the doc directory). Obtaining Tony Bybell's gtkwave gtkwave.app, the documentation is found in /Applications/gtkwave.app/Contents/Resources/doc, both a source. You'll also want to understand the implications of the -r run command (section 3.1.3), with no optional secondary unit passed on the command line VHDL defaults to the last compiled architecture. You'll end up with a work-obj93.cf library configuration file in the current working directory and no other output files. On standard output (the TTY session in your terminal window).

Saving the source code for the hello_world command to the file hello.vhdl and executing the ghdl -a ghdl -e ghdl -r hello_world The result of the simulation appears on the screen: Hello world! The simulation is launched using this command: > ghdl -r hello_world On GNU/Linux, the result is an executable program called hello which can be run: $ ghdl -r hello_world With this option, GHDL creates code in order to elaborate a design, with the ‘hello’ entity at the top of the hierarchy. Then, you have to build an executable file.
The object file is not created on Windows. On GNU/Linux, this command generates a file hello.o, which is the object file corresponding to your VHDL program. This command creates or updates a file work-obj93.cf, which describes the library ‘work’. First, you have to compile the file this is called analysis of a design file in VHDL terms. Suppose this program is contained in the file hello.vhdl. Defines a design entity, without any ports. Use - Imports the standard textio package. To illustrate the large purpose of VHDL, here is a commented VHDL "Hello world" program. Also 2.1 The hello world program: 2.1 The hello world program

In the ghdl manual see 1.3 What is GHDL?, (The Windows(TM) version of GHDL is not based on GCC but on an internal code generator). Where ever 'Windows' appears it should be read as 'Windows or other mcode version'.

As an oversight I didn't think to amend the ghdl manual to include the word mcode wherever Windows appeared and release modified manual.
In ghdl.html you could search for every occurrence of 'Windows' to find reference to the mcode version. The documentation for ghdl is found in /usr/local/ghdl/doc/, there's the ghdl man page which is linked elsewhere, ghdl.html and ghdl.texi which are the ghdl manual and not linked elsewhere. This version is derived from svn129 (following the ghdl-0.29 release), and contains an i386 binary. cf files for pre-analyzed libraries, by default these will show up in /usr/local/ghdl/libraries, the executable ghdl found in /usr/local/bin links to /usr/local/ghdl/translate/ghdldrv/ghdl_mcode, and /usr/local/ghdl is a stripped down tree resulting from the compilation of the ghdl_mcode version. All you are going to see is the work-obj93.cf file for the working directory and any. In an mcode version of ghdl the -r run command also elaborates.
The elaborated model only exists in memory at run time and the -e elaborate command is superfluous other than an entry in the working library. It's the mcode version (like on Windows), which means it doesn't produce object codes or a standalone executable of a VHDL model with the consequence you can't bind foreign objects (subprograms) to the model.

There's a version of ghdl for OS X running on Intel processors for versions 10.5, 10.6,10.7 and 10.8 available from (can be downloaded at GHDL for Mac OS X).
