HLA causing Logic 2 to freeze

Extensions
1

I am developing an HLA extension and I noticed that sometimes Logic 2 will start to blur the data/clock lines into just solid color and eventually freeze.

@ruvim.piholyuk Hey there, this definitely shouldn’t be happening. Would you be able to share a capture file with us so we can reproduce it locally? And if the HLA is required to reproduce the problem, share that as well?

It seems to fail when using the PIP3 analyzer option.

Thanks

Thank you @ruvim.piholyuk,

I can reproduce the issue over here. I won’t be able to look into the root cause right away, but I’ll let you know once I have an update.

Hi @ruvim.piholyuk ,

It looks like the primary issue is that the HLA you posted has 2 issues:

  1. It produces frames where the end_time is less than begin_time.
  2. It produces frames that overlap with previous frames. In particular, it looked like there were a lot of duplicate frames.

These are 2 cases we do not support, and can cause rendering issues when they are encountered. Unfortunately Logic 2 does not currently detect these cases. I will make a change to properly detect these cases and display an error - that should go out in the next release. I’m sorry we didn’t have that in sooner!

Please let me know if you have any more questions,

Ryan
