Crash in timing report when vigorously exercising yellow highlight

Open oharboe opened this issue 1 year ago • 1 comments

Describe the bug

  1. untar https://drive.google.com/file/d/1lDdIysDfIFES_vrCKpRbrqg5Ie4ebnEw/view?usp=sharing
  2. Run: ODB_FILE=results/asap7/mock-array_Element/base/6_final.odb ./run-me-mock-array_Element-asap7-base.sh
  3. Create timing report
  4. Select first timing path and first line in data path details, see below.
  5. Use keyboard arrows to move/up down until you get a crash

Expected Behavior

No crash.

Environment

OpenROAD v2.0-13378-g6bc228c51

To Reproduce

See above. It takes multiple rounds of navigating with kebyoard arrows to top/bottom, say 10x all the way to the bottom and back up?

Relevant log output

No response

Screenshots

No response

Additional Context

No response

@AcKoucher please see if you can reproduce this.

maliberty avatar Apr 24 '24 16:04 maliberty

@maliberty @oharboe I can't reproduce this.

AcKoucher avatar May 13 '24 17:05 AcKoucher

@maliberty @oharboe I can't reproduce this.

What to do now? I dont think it is fixed... Interactive debug session? When would be a good time?

@maliberty Can you reproduce it?

oharboe avatar May 13 '24 17:05 oharboe

No I can't reproduce it either. Tomorrow 9am?

maliberty avatar May 13 '24 18:05 maliberty

Can't reproduce on OpenROAD v2.0-13763-g1c9637d0f

oharboe avatar May 13 '24 19:05 oharboe

@maliberty @AcKoucher Was anything done to fix this?

Did you try with v2.0-13378-g6bc228c51?

oharboe avatar May 13 '24 20:05 oharboe

@AcKoucher @maliberty My concern is that this crash is still there and by using the latest version, initial conditions were changed and this caused the crash to no longer appear, even if the problem is still there.

oharboe avatar May 13 '24 20:05 oharboe

I doubt it relates to the specifics of the design. My guess is the timer fix also worked here but I can't say for sure.

maliberty avatar May 13 '24 20:05 maliberty

I can't reproduce it even with OpenROAD v2.0-13378-g6bc228c51 on my home workstation.

oharboe avatar May 13 '24 20:05 oharboe

@maliberty I imagine that timing is critical to reproduce the problem... I tried varying zoom levels, no luck in reproducing.

oharboe avatar May 13 '24 20:05 oharboe

With no way to reproduce it there is no real next step to take.

maliberty avatar May 13 '24 20:05 maliberty

  • disable power and ground nets.

To reproduce, disable as much rendering as possible so that the yellow updates quickly:

image

oharboe avatar May 14 '24 19:05 oharboe

I can only make it crash with:

./build_openroad.sh --local --latest

If I try:

./build_openroad.sh --local --latest --openroad-args -DCMAKE_BUILD_TYPE=RelWithDebug

No crash...

oharboe avatar May 14 '24 20:05 oharboe

I saw this segfault in the debugger when I clicked Timing Report -> Update. Not related though. Making note of it here.

@AcKoucher @maliberty Matt was able to make it crash once on his end and I can make it happen fairly regularly. If I use the mouse to highlight up and down across the REG lines, it seems to happen fairly consistently on my machine.

oharboe avatar May 14 '24 20:05 oharboe

It is possible to get the crash in the debugger with symbols:

oharboe avatar May 14 '24 21:05 oharboe

@maliberty So how can highlight be nullptr on line 589, when it clearly wasn't nullptr in line 583?

oharboe avatar May 14 '24 21:05 oharboe

@maliberty @AcKoucher Looks like the rendering thread is using the same list that is being manipulated by the main thread and that the "swap" thing is not being done for highlight_stage_?

If the list is cleared from the main thread, then I can see that a null pointer exception happening.

oharboe avatar May 14 '24 21:05 oharboe

threading most likely

maliberty avatar May 14 '24 21:05 maliberty

What is the "swap thing"?

maliberty avatar May 14 '24 21:05 maliberty

What is the "swap thing"?

See screenshot above from the render loop.
