Free timing diagram drawing software

Hi,

I'm not sure if this is the best place to ask, but anyway, does anyone know of any free software that draws timing diagrams?

Thanks,

Michael.

Did you mean timeline diagrams? You can use

for that. Its a online diagramming tool with real-time collaboration enabled. try it

Who? The person who posted the question 12 years ago?

There was a guy writing a timing diagram editor some time back. I think it was called timing designer or similar, but I see "timing designer" is an expensive product name. I downloaded the early versions and found it to be very lacking. I tried to give him constructive feedback. After pushing it for two or three years he seemed to stop posting about it.

Is this what the original post was about?

Well the original post was looking for "any free software that draws timing diagrams." And the only reply at that time (12 years ago) was to check out the lite version of

which still seems to exist.

I do remember Timing Designer as being not very good, and eventually quite expensive. At the time I was using dV/dT on a Mac, which worked quite well for what it did. Nowadays I usually use a simulator to create timing diagrams more complex than any I might draw by hand.

You guys are aware of the free TimingAnalyzer program for Windows, right? If not, have a look at

I'm no expert, but it looks like a big improvement over hand drawn diagrams for just about any situation (and certainly would be easier to revise).

I think that is the one I saw some years ago. I think it was a labor of love for the author and he got little respect for it at the time. I'm glad to see that he stuck with it and turned it into something truly useful.

I think someone posted a list of timing diagrammers some time ago and I looked into a few. One was WaveDrom Editor where you edit a JSON description of your waveform and the waveform updates in real time. I really like it.

It's a browser app and available

(or you can run it whereever since it's free) and it exports the diagram to SVG. From experience SVG is well supported by Microsoft for importing vector drawings into documents.

Hi Rick,

Wow! It has been a long time. I remember our converations about this a lon g time ago. I didn't realize how much work this was gone to be but I do en joy development and will probably always be working on some kind of CAD too l. I'm actually about 5 years away from retirement now and plan to do this CAD tool development full time then to keep busy.

The TimingAnalyzer is alive and doing well. Progress is still very slow si nce it is a part time effort but that is nothing new and I have learned to accept that. I have focused most recently on timing analysis and added a timing engine t hat is accurate to the +-fS. There are ways to create timing diagrams from Verilog or VHDL or directly from VCD files and there are app notes describi ng how to do that with python scripts examples. The most recent app note, I ntro to Timing Analysis" includes real examples with python scripts to run them.

There are other programs out there you can use to draw timing diagrams so t he focus going forward will be on:

logic simulation with model delays transaction based diagrams. source code generation python scripts for all operations

Keep in touch,

Dan Fabrizio

What's odd is the way it's built for Windows, and the solution to run on Linux or Mac is to use WINE. But it's implemented in wxPython, which is a cross-platform library. So it should be straightforward to run natively on Mac and Linux. Maybe the author doesn't have a system to test, but I'm sure the 'open source community' (whoever that might be) could help out with that.

But it's not open source, or did I miss something?
