This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

"A timing diagram" probably means something very different to the next man in thge street than it means to me.  If you could describe what you mean in a little more detail, and post up EITHER a description of how you've thought about the problem so far (if you'v got stuck before you've started to code) OR some code and a note of the problems you're having, I'll have a look and see if I have any suggestions to help you with the next step.

Have a look at http://www.wellho.net/cgi-bin/opentalk/YaBB.pl?board=Assist;action=display;num=1081843563 which tells you something about the time taken to provide answers on this board.

tHANKS gRAHAM FOR REPLYING .......
.................AND I SAW THE LINK U HAD SEND REGARDING THE TIME TO REPLY .............
..............
             i HAVE TO DESIGN A "VALUE CHANGE DUMP"(vcd) FILE DISPLAYER. MY TIMIG DIAGRAM WILL BE
DISPLAY VALUE OF EACH SIGNAL OVER A RANGE OF TIME
(THERE WILL BE HORIZONTAL SCROLL TO SEE VALUE FOR LONG RANGE OF TIME).I HAVE TO DESIGN THIS TOOL FOR LINUX ENVIRONMENT.........SO I HAVE CHOOSEN TCL/TK TO DESIGN THE GUI PART .....I'LL INTEGRATE IT WITH 'C'...........TO DO OTHER THINGS.........MORE OVER MY TIMING DIAGRAM WILL LOOK LIKE THIS :
                                              ___        ___
SIG1 ___________________|     |___|     |___________

                _______                ___
sig2_____|             |_______|      |_____________


or U CAN CHECK THIS LINK OUT THIS IS SOME WHAT HOW IT WILL LOOKLIKE  :
http://www.lerc.nasa.gov/WWW/CEAWeb/B5830/people/vnguyen/Sulfur/Sulfur-2.jpg

I WOULD LIKE TO KNOW iF U HAVE ANY OTHER SUGGESTION (LIKE A TOOL OR PROGRAMMING LANGUAGE )THRU WHICH I CAN DESIGN THIS THING FOR LINUX
ENVIRONMENT............

Personally, I would use Tk (so I'm agreeing with your decision) and use a canvas widget to draw the signals ... I would suggest all the signals on a single canvas so that you keep them on the same time axis; you'll need some scaling procs to convert world co-ordinates to pixels.  If you've got tix, then a tixScolledWidget will let you scroll as you decribe without having to write all your own scolling code, and Tk will allow you to add other controlling widgets too.

I do wonder why you're integtating with C. Tcl and Tk are powerful languages - are you sure you need C as well?

thanks a lot Graham............. ............
.............and i'll see to it  if  I will use 'c' or not........
...............I had thought i will write the complex part i.e algorithms in timing diagram .in 'C'  but know as u have said I'll see to it................
....................thanks any ways thanks a lot .........
