Anyone know of a cheap (or free) Timing Diagram tool?

I need to communicate with my digital counterparts on an IC design ;-)

NICE! Thanks!

Now. A dumb question... do I just copy this to the \Windows\Fonts
directory, or is some other step required?

I think I just copied it into the folder that is shown when you follow
Start --> Settings --> Control Panel --> Fonts
but maybe it must also be registered.

Adding New Fonts
----------------
Windows supports TrueType fonts or fonts that are specially designed for
Windows, and these fonts are available commercially. Some programs also
include special fonts that are installed as part of the program
installation. Additionally, printers frequently come with TrueType or
special Windows fonts. Follow the directions that come with these products
to install these fonts.

To manually install or re-install a font:
1. Click Start, and then click Run.
2. Type %windir%\fonts, and then click OK.
3. On the File menu, click Install New Font.
4. In the Drives box, click the drive that has the floppy or CD-ROM
that contains the fonts you want to add. If you are installing fonts from a
floppy disk, this is typically drive A or drive B. If you are installing the
fonts from a compact disc, your CD-ROM drive is typically drive D.
Double-click the folder that contains the fonts.
5. Click the font you want to add. To select more than one font at a
time, press and hold down the CTRL key while you click each font.
6. Click to select the Copy Fonts To Fonts Folder check box. The
Windows\Fonts folder is where the fonts that are included with Windows are
stored.
7. Click OK.

Note On Microsoft Windows NT 4.0, Microsoft Windows 2000, Microsoft Windows
XP, and Microsoft Windows Server 2003, you must be an administrator to add
and remove fonts.

Arie's hint is great. But it'll be lots of typing. If it isn't for doc
purposes but just for mutual understanding there is an easier way. This
Saturday me and my layouter (with him being in Vermont) just could not
get onto the same page with a weird kind of laser diode mounting
(z-bend, then rotate a bit and lay flat over some discretes).

So I sketched it up, scanned that in and zipped it over. Tada! Problem
solved, layout is now done. But the fab people haven't come back with a
quote for hours now. Hope that doesn't spell trouble.

My Computer -> Control Panel-> Fonts and drag & drop the ttf file in,
it should install.

I sketch on grid paper, photograph, and email. One of my customers
jokingly asked me what CAD package I use, and I answered "Sharpie."

Didn't Bob Widlar call that his "Mexican Computer"?

I really like the scanner. Got myself one of those biz-hub style things
and it sits within arms length from me. It's connected to the LAN.
Sketch up, click the scan to email thingamagic on the PC, bzzzzt, click,
click, click, done.

Agree. Except that I don't know what an eraser shield is. Do I have to
feel dprived now?

directly to laser printer). I use it rarely, but it sure comes in
handy when it's needed.

Yep, it does that, too. Just have to hit another button and it copies.
Faxes, scans, prints and copies at a pretty good clip. This has freed up
a lot of space in my office plus I have better redundancy now. It has so
many buttons that I just discovered a new one after over a year: It can
scale copies. Yeehaw. Didn't know that.

An eraser shield is a small piece of stainless steel, about the size of a
credit card and very (0.010" or so) thin. It has various size cutouts in
the steel, some circles, some radiuses, some straight lines, some !
teardrops, etc.. You put the shield over the part you want to erase a tiny
portion of and erase like hell without worry about erasing too much.

I've still got a working electric eraser (both plug-in and cordless) if
anybody needs one. Otherwise they go to the engineering museum when I kick
off.

Nah, that was Teledeltos paper. It was electrically conductive, with a
sheet resistance of something like 10k ohms per square. You cut it with
an X-Acto knife, put a voltage across it, and it solved the 2D Laplace
equation for voltage drop vs position pretty well. I went looking for
some a few years ago--it had been picked up by a British outfit,
allegedly, but they didn't seem to have any for sale any more.

Thanks for explaining. Didn't know that. But I could imagine that the
sharp edges will increase the amount of eraser turds that go all over
the place, where my wife says "look at the mess you made now".

I've never gone that high-tech :)

LOL, on the contrary, if you don't know what an eraser shield is you
must be a genius working with India ink from the start. ;)

Long before CAD came on the scene, these were my two best friends:


The logic template was the bugger and the eraser shield was the
debugger. ;)

At the university we were forced to use ink pens. The tricky ones from
Rotring or Staedtler that would only work if held at exactly 90 degrees
to the vellum, would leak a lot and dry up in no time. Plus ruin the
occasional shirt. Same during the internships that were mandatory. So
yeah, I kind of got used to that.

For some reason those links don't work for me. When I click on these
nothing happens :-(
