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.

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
