Dynap-SE2 Simulation Module

This module implements a neuron model that solves analog VLSI circuit equations to provide a reliable simulated machine. JAX-backend Dynap-SE2 simulator named devices.dynapse.DynapSim does not simulate the hardware numerically precisely but executes a fast and an approximate simulation. It uses forward Euler updates to predict the time-dependent dynamics and solves the characteristic circuit transfer functions in time.

This module also provides a surrogate function implementation to support gradient based optimization and a mismatch prototype to support analog device mismatch simulation.
