This adds to the Lava process library a Leaky Integrate-and-Fire neuron with adaptive threshold and adaptive refractoriness (ATRLIF neuron). Both a floating- and a fixed-point CPU process model implementation are contained.

I also have a working NC process model, based on microcode from Lava-DL, which I kindly received from @bamsumit. For that, I'd like to know how to proceed to integrate the model into Lava-Loihi.

As a side note, the neuron model has already been integrated into Brian2Lava.

Pull request checklist

Your PR fulfills the following requirements:

  • Issue created that explains the change and why it's needed
  • Tests are part of the PR (for bug fixes / features)
  • Docs reviewed and added / updated if needed (for bug fixes / features)
  • PR conforms to Coding Conventions
  • PR applys BSD 3-clause or LGPL2.1+ Licenses to all code files
  • Lint (flakeheaven lint src/lava tests/) and (bandit -r src/lava/.) pass locally
  • Build tests (pytest) passes locally (except for tutorial02_processes.ipynb, for unknown reasons)

Pull request type

  • Bugfix
  • Feature
  • Code style update (formatting, renaming)
  • Refactoring (no functional changes, no api changes)
  • Build related changes
  • Documentation changes
  • Other (please describe):

What is the current behavior?

--

What is the new behavior?

  • ATRLIF neurons can be used within Lava. Users can decide between floating- and fixed-point CPU implementation.

Does this introduce a breaking change?

  • Yes
  • No

This looks good. Thanks for the contribution.

Just some minor changes to be open. I will push for a second reviewer to look over the PR in the next days.

I have nothing to add, everything looks nice. There are tests and even a tutorial. Thanks.

@PhilippPlank @weidel-p thanks for reviewing. I've pushed the adjustments you asked for, so I guess it can be merged now.

Regarding the NC process model, do you want to integrate this into Lava-Loihi? How can we proceed for that?

@jlubo Could you please update the branch with main? I had to fix a CI problem and this is now blocking this PR. Thanks!
