Solaris/Linux flowchart (critical instant scheme) draw tool

Solaris/Linux flowchart (critical instant scheme) draw tool

[Emanuel Berg]

This might be (a bit) OT on comp.lang.ada, but as Ada is
- or should be - the number one real time programming
language, I thought probably you could help me. (Also,
there doesn't seem to be that much traffic on
comp.realtime, though I know there are some good people
there, too.)

Anyway, take a look at this:

Is there a tool to draw such diagrams? (In general, the
details may vary.)

I don't need a tool to compute runtimes, preemptions,
etc., out of raw data, and then draw, no, I'm going to
draw everything manually, only, I thought there might be
a tool to do it.

Otherwise, I thought about buying those big
white-blue-ish sheets that engineers used (and should
use, still, if they have style), and draw them by
hand. Also, I contemplated the idea of drawing them on a
whiteboard, and then shoot it with a camera.

I don't know. Doing it with gimp or even Dia doesn't
seem that attractive.

It looks like you might find TeXCAD the appropriate tool:

So far only with Windows binary, but you can run it through Wine on Linux.
BTW, TeXCAD is written in Ada :-)

If LaTeX is an option for you, this could be done with pgf­gantt:

Of course LaTeX is an option! Perhaps this is the best
advice yet, as I am not that inclined to much about with
Wine.

Yes, that was a good start. There isn't any support for
CIS diagrams in pgfgantt, but with lots of
trial-and-error modifications and hacks, I did an
example that could serve as skeleton code, so I should
be able to produce the 15 or so scenarios I have to
cover hopefully by just putting in digits in slots.

Note though, I'm no LaTeX expert, so this is rather a
demo that this type of task (uh) can be done with this
method, and with a reasonable effort.

The diagram:

The LaTeX code:

Thank you Alex. I was about to draw this all by hand :)

A generic vector-drawing tool that I like with a very good (IMHO) GUI is inkscape (http://inkscape.org/).  Even if it is not specialized for the specific type of diagrams that you need, I think you should find it easy to use to draw them.

Its native format is SVG (Scalar Vector Graphics http://en.wikipedia.org/wiki/Scalable_Vector_Graphics), but it can export in many formats including PDF, EPS/PS and PNG.  I use it to create the images that I import in my LaTeX docs.
