I'm looking for a tool which will read in my vhdl sources and convert
them into documentation. This may be either html or another standard.
I'd love to see it generate graphic representations of FSM's. Does such
a tool exist? Is it any good? Any experiences?
Cheers,
Michiel
http://rassp.scra.org/ is a good start point. You'll find there a
vhdl2html converter.

I'd love too. But I'd prefer a mind reader that writes the VHDL
for me (bug free if possible). So, I could concentrate on my nice
bubble diagrams ;-)

I'm afraid this kind of tool would be very very difficult to design.
And not so useful (graphic representations of FSM are unreadable
when you reach 50-100 states). But people are so fond of graphical
interfaces that it could exist somewhere after all.

you might be interested in Mentor Graphics' Renoir (www.renoir.com).
the tools primary features are:
- let's you draw block diagrams, flow charts, truth tables, and state
diagrams and generates the corresponding vhdl/verilog
- reads in vhdl/verilog and generates the corresponding block diagram,
flow chart, or state diagram.
i've been using Renoir for about three years now and it's only gotten
better with time. the latest versions include interfaces to simulation
and synthesis tools. one of the coolest features is the ModelSim
interface (i beleive it works with others as well) that lets you observe
your FSM while the code executes. makes finding unreached states, etc.
a breeze.
For documentation purposes, the most recent Win32 version of Renoir
allows you to embed any graphical item into a Word document just like a
spreadsheet or other object.
licensing is an issue but not a big one. for instance, you can have one
license that you use to create and modify designs. if someone else
would like to view the design database, they simply need a trial version
of the tool which can read the data. if i recall correctly the demo is
fairly capable with only the "generate hdl" function stripped.
the only draw back is viewing a large diagram. in the tool you can zoom
in but on paper it will be almost illegible unless you print it to a
very large sheet of paper or multiple sheets and tape them together.
i have heard of similar tools but have not tried them. two others are
Aldec's Active VHDL (www.aldec.com) and Visual Software Solution's
StateCAD (www.statecad.com).

Lots of fun. Block Diagrams, State machines, and Flow charts.
Machine generated schematics are never fantastic, but as long as your
FSM does not have too many states as to fill the page with hundreds of
bubbles and transition, you may be OK. Renoir users can draw
hierarchical FSMs so documentation can be clean even for very complex
machines. Being an OLE capable application means that you can pull
graphics right out of Renoir and into a Word Document. :-)
Of course ideally you would have done your design using Renoir.....

No mind reader, but if you want to draw bubble diagrams: Renoir.

Not with hierarchical states.
Try Renoir, you might just like it :-)

You can try Novas's product - Debussy
(http://www.novas.com/products/index.htm). It can do nice transfer from
HDL text to graphic. It has schematic view (nSchema) and automaticlly FSM
extractor (nState).
