RE: [vhdl-200x] Standardize GHW format?

So, my reading that it is under the GNU General Public License. That makes it pretty ineligible for standardization unless the license holder would donate the technology and assign the copyright to the IEEE. While you are technically correct that it is not proprietary it is definitely encumbered with copyright issues that would have to be addressed.

Hi Dave,
The GHW format is not proprietary. It is open-source, so we can take a look at their source code to figure out how they implemented the format.
I'm currently going through that right now during my free time.

As have all of us that support vhdl. There is no neutral format, just a lot of proprietar ones. Standardizing one of them would be challenging.

Hi all,
I was thinking it may be a good idea to standardize the GHW format that is now being used by GHDL (VHDL simulator) and the GTKWave waveform viewer.

Verilog has standardized the VCD waveform format, but some VHDL types can't be exported to that format since it's mainly Verilog-specific.
This was the reason why GHDL chose to define a new waveform format.

More information on GHW is here:
http://ghdl.free.fr/site/pmwiki.php?n=Main.Features
http://ghdl.free.fr/site/pmwiki.php?n=Main.WaveViewer

Of course, we can study this new format and see whether we would like it standardized, or we'd rather define a new format.

Just my 2 cents.

regards, dan
