Do you have any samples of the new diagrams? (Always nice to see how things are going in SpiNNaker land all these years later!)

Hope all is well and sending all the best!

That's really cool! (Also what a big simulation!)

If it's of any use I don't know if you remember this tool: https://github.com/project-rig/rig-par-diagram It's a little rig-oriented but might be useful if you ever want routing information (or core-level info).

I had forgotten that one, but will definitely look it up - thanks!
