Steve,
The only code timing-diagram-like tool I am aware of is Windriver's WindView
for VxWorks.
I have successfully used digital logic timing diagrams in the past to view
task timing and interaction. They are especially useful for multiprocessor
systems.
I think the determining factor would be the metadata you want associated
with transitions. (channel wait, timer interrupt, etc.)
Also, how precise you want the timing to be. I usually use the TSC (Time
Stamp Counter) on Intel processors which gives very fine-grained timing
without fear of the counter wrapping.
Cheers,
Daryl

Subject: [9fans] OT: hard realtime, timing diagram GUI.
Hi,
Just trying to tap the collective brains fo the plan9 community.
Anyone done any hard realtime programming? I am looking for a simple GUI
tool which will read a text file I can generate from my code and display a
timing diagram. This should allow either events triggered by the clock, by
an interrupt, or by another event.
Anyone know of such a tool? I see masses of tools for drawing digital logic
timing diagrams but nothing that seems to give me what I need for realtime
code.
Thanks,
-Steve
