Best Free or Affordable Alternatives to TimingDesigner for Drawing Timing Diagrams

I'm looking for some free or cheap software to draw timing diagrams. Now I'm using a very nice  program at work called TimingDesigner but I'd like something similar to use when I'm not at work. I'm assuming that this program is very expensive since their web site has you call to get a price.
Now I suppose that I could just draw something by hand in a drawing program but that tends to get a bit fiddly if you have to make changes. So I'd like something easier and better.
I did a search and came up with the following:Timing Editor. http://timingeditor.sourceforge.net/This looks like it has possibilities. Has anyone used it?
WaveDrom  https://wavedrom.com/tutorial.htmlText based. Might work if everything I wanted to draw lined up on the clock edges. I need to add propagation delays so this isn't going to work for me.

Timing Analyzer https://www.timing-diagrams.com/features.htmlThis also might work. Does anyone have any experience with it?
Any other software out there that I should look at? The main requirements are that it needs  to be shareware or open-source, reasonably easy to use and able to show the effects of propagation delay and the like. Web-based would be OK as long as I can create an image that can be pasted into a document.

ElizabethAs the saying goes "If you only have a hammer, everything looks like a nail..."Well let me tell you I have seen Excel used for timing diagrams  where you use the cell border to indicate the waveform. You can manipulate the cell width to indicate the propagation delays.
I know this is very "crunchy" and I apologise in advance. I would certainly not put it as an idea in one of my blogs- but if you're desperate...

AubreyI've heard of the Excel trick and may even have tried it once. I'm not that desperate  yet. LOLI suppose there is always graph paper and pencil. I've got a scanner so I could scan it in. It might be easier than learning new software.
The draw, scan, oops process might be a bit painful though. Especially if I make a reasonable attempt for my printing to be legible.

You could make it slightly easier by creating macros for the basic building blocks like a falling edge and a rising edge. I am still not endorsing the approach!

ElizabethNow I'm using a very nice  program at work 
Some software licences will allow you to run a copy at home as well as work. IIRC Microsoft does it as well as Altium. You should check.

I see TimingDesigner does offer a free trial, but it does not say how long for, and you've probably already used it Elizabeth?  If not it might work long enough for you to write your article?

A quick web search turns up Draw timing. Never used it, but it looks like it would work very well for brief examples of a few dozen clock cycles.
If you want to do your drawings in an Office-like toolset, try OpenOffice.org, specifically the Drawprogram. If you want to generate the best graphics (And don't mind if it takes a while), try Inkscape as suggested by digikata. Professional datasheets will probably be best served by the tikz-timing packagean as suggested by jluciani, or the older (but less complex) timing.sty, both with (La)TeX (Try Lyx for a shorter learning curve, if you're new to TeX. Be warned that it's a steep curve no matter what, but it's worth it!)
but that's oriented more towards simulation of Verilog/VHDL/schematics, rather than just drawing waveforms.

Inshah,When I did a search for "Draw Timing" that you mentioned I found this:
https://electronics.stackexchange.com/questions/3564/software-to-create-timing-diagramsIt appears to me that your post was copied from the first answer in the stack exchange thread. The only thing you did was delete the third paragraph.
Copying what someone else wrote and presenting it as your own is called plagiarism and is not acceptable behavior. Please cease and desist from this behavior. If you want to point out something that you've read that is relevant to a forum question, the proper way to to that is to provide a link as I did above.

Elizabeth,May I suggest Waveme (waveme.weebly.com).It's a free timing diagram program that I wrote.If you give it a try, I'd be happy to hear your feedback.

I've used Wavedrom in the past and I was quite happy with it. My diagrams were simple UART, I2C, and SPI timings, but I found quite easy to use Wavedrom. With a little creativity I guess you can make some pretty complicated diagrams.

If you don't think Wavedrom is powerful enough, I'd recommend bringing ou the big guns and using tikz-timing. It uses textual description and the examples at the end of the manual are pretty complex. And it's tikz, which means you get vector graphics output and you can make ridiculously complex diagrams.
