Hi Chris,

We have a release candidate out for NESTML 8.0.0, as there were some big changes since the last version, could I ask you to work with that? It should be easy to install using "pip install --pre nestml"; please let us know if you run into any issues.

To generate the code for an STDP synapse, you need to tell the code generator that there is one spiking input in the synapse model that should be connected to the postsynaptic partner. Please see here for documentation:

https://nestml.readthedocs.io/en/latest/running/running_nest.html#generating-code-for-plastic-synapses

And see here for a usage example:

https://nestml.readthedocs.io/en/latest/tutorials/stdp_windows/stdp_windows.html

Hope this helps!

With kind regards,

Charl

I’m working with the nestml 7.0.2. I got the example models from https://github.com/nest/nestml/blob/v7.0.2/models/neurons/hill_tononi.nestml this git tree. I tried three different stdp models including stdp_triplet_naive.nestml. All give
AssertionError: Synapses only support one spiking input port
