SC-NeuroCore

Stochastic computing and neuromorphic hardware co-design toolkit

Version: 3.15.25

SC-NeuroCore is a research-to-hardware software stack for designing spiking and stochastic neural systems, validating their numerical behaviour, and moving selected models toward FPGA, ASIC, and embedded neuromorphic deployment. It combines a Python public API, an optional Rust acceleration engine, SystemVerilog generation paths, benchmark evidence, and polyglot research mirrors for selected kernels.

It is useful when a team needs to answer practical questions such as:

Can a stochastic bitstream representation approximate this neural computation within a bounded error budget?
Which neuron, synapse, encoder, or network path is numerically appropriate for a target workload?
Can a model be converted into auditable hardware artefacts rather than remaining only a Python simulation?
Which evidence is available for speed, parity, synthesis, safety-case readiness, or cross-framework comparison?
Which capabilities are stable package surfaces and which remain source-checkout research surfaces?

Who It Is For

Audience	Primary value
Neuroscience and SNN researchers	Reproducible neuron and network experiments with explicit numerical guardrails.
Hardware and FPGA engineers	Bitstream arithmetic, fixed-point export, RTL generation, and synthesis evidence workflows.
ML and edge-computing teams	SNN training, ANN-to-SNN conversion, acceleration options, and deployment trade-off studies.
Safety, verification, and industrial teams	Evidence bags, fail-closed readiness checks, formal-verification collateral, and documentation boundaries.
Commercial evaluators	A mapped path from modelling to hardware-oriented evidence, with clear gaps before field deployment.

What Makes It Distinct

Stochastic computing first: bitstream encoders, probabilistic arithmetic, Sobol/LFSR sources, and bounded error reasoning are first-class components.
Neuromorphic breadth with guardrails: the repository contains a wide neuron/model catalogue, but public docs separate stable package surfaces from opt-in research paths.
Hardware-oriented output: selected workflows generate Verilog/SystemVerilog artefacts, synthesis reports, and hardware-readiness evidence instead of stopping at simulation.
Evidence-indexed benchmarking: public benchmark claims are tied to committed artefacts under benchmarks/results/ or hardware reports under hdl/reports/.
Polyglot parity research: Julia, Go, Mojo, Rust, and Python counterparts exist for selected kernels to test implementation fidelity and performance trade-offs, while the default install remains Python-first.

Application Areas

SC-NeuroCore is positioned for neuromorphic R&D, stochastic accelerator design, edge inference studies, BCI and spike-codec prototyping, safety-case tooling, and hardware/software co-design. It is not a certified medical, automotive, aerospace, or rail product by itself. Domain profiles in the documentation state required evidence and missing evidence explicitly so commercial or regulated deployment work can start from an auditable gap list.

Current Evidence Boundary

Surface	Current status
Public Python package	Version 3.15.25 package surface with base NumPy/SciPy dependency boundary.
Optional acceleration	Rust engine and optional heavy backends are opt-in; Python fallbacks remain available.
Hardware evidence	Committed synthesis and report artefacts exist for selected flows; power/energy claims require matching committed reports.
Benchmarks	Only committed JSON/CSV/report artefacts are public evidence. Local exploratory runs must not be promoted without raw artefacts.
Polyglot surfaces	Source-checkout research and parity surfaces, not default user install requirements.
Regulated deployment	Readiness tooling and evidence categories only; no certification or field approval claim.

Quick Start

pip install sc-neurocore

For biological closed-loop BCI implementations (experimental), install the bioware optional dependencies:

pip install "sc-neurocore[bioware]"

from sc_neurocore import StochasticLIFNeuron

neuron = StochasticLIFNeuron(v_threshold=1.0, tau_mem=20.0, noise_std=0.0)
spikes = sum(neuron.step(0.8) for _ in range(500))
print(f"{spikes} spikes in 500 steps")

Zenith Quickstart

Train biologically plausible rules using PyTorch surrogate autograd, then export the exact layer to hardware:

Bio-hybrid Closed-Loop with ArcaneZenith (Experimental)

The bioware module securely bridges biological real-world MEA setups into Stochastic Computing and Optogenetic laser outputs natively. It supports PCA/K-Means spike sorting, runtime health tracking, pharmacological wash simulations, and ArcaneZenithCognitiveCore bridged bindings.

import torch
from sc_neurocore.plasticity import create_plasticity_layer
from sc_neurocore._native.learning_bridge import RULE_STDP

# 1. Train entirely in standard DL execution architectures
bcm_layer = create_plasticity_layer(count=128, rule_type=RULE_STDP, backend="torch", autograd=True)
# ... standard cross-entropy loss.backward() loop

# 2. Deploy natively to SC-NeuroCore hardware limits
exascale_layer = create_plasticity_layer(count=128, rule_type=RULE_STDP, backend="rust", weight=bcm_layer.weights.detach().numpy())
exascale_layer.save("hw_layer.scal")

See the full end-to-end integration demo in examples/zenith_hybrid_resnet.py.

# Add only the extras needed for the current workflow.
pip install "sc-neurocore[core]"      # explicit base profile
pip install "sc-neurocore[nir]"       # NIR interop
pip install "sc-neurocore[training]"  # PyTorch-backed training
pip install "sc-neurocore[studio]"    # local web studio
pip install "sc-neurocore[full]"      # local research environment only

See Install Profiles for the full optional dependency matrix and research-only boundaries.

Rust Engine (39–202× faster)

The optional Rust engine provides SIMD-accelerated simulation, 174 neuron models via PyO3, and fused E-I network simulation. Pre-built wheels are available through repository release assets or source builds when present in the local environment.

When installed, SC-NeuroCore automatically uses the Rust engine for:

NetworkRunner: 161-model fused Rayon-parallel simulation loop
E-I network: single Rust call for connectivity + Poisson + Euler + spike detection
Batch simulate: model dispatch loop in compiled Rust
SIMD bitstream ops: 190 Gbit/s popcount (AVX-512)

The pure Python package works without the engine — NumPy fallbacks are used for all operations. Install or build the engine only when you need the performance advantage. See Install Profiles for the base install, optional extras, and source-build path.

pip install sc-neurocore publishes the Python suite under the public sc-neurocore package name. The optional Rust engine remains part of the repository / release-asset / source-build flow rather than a separate PyPI runtime dependency. Source-only extended modules such as analysis, viz, audio, dashboard, and swarm still require a source checkout.

Development Setup

git clone https://github.com/anulum/sc-neurocore.git
cd sc-neurocore
pip install -e ".[dev]"    # editable install with all dev tools
make preflight             # verify setup (lint + tests)

If you are changing the Rust bridge locally, install bridge/ in the same environment or run source-tree commands with PYTHONPATH=src:bridge.

Visual SNN Design Studio (Experimental)

Status: Development preview. The Studio is functional but under active development. API and UI may change between releases until the v4.0 stable API freeze.

A web-based IDE for designing, training, compiling, and deploying spiking neural networks — from ODE equations to FPGA bitstream in a single browser tab.

pip install sc-neurocore[studio]
sc-neurocore studio              # opens browser at http://127.0.0.1:8001

Feature	What it does
118 Model Browser	Browse all neuron models by category, simulate with parameter sliders
18+ Analysis Views	Trace, phase portrait, ISI, f-I curve, bifurcation, heatmap, STA, frequency response, characterisation dashboard
Compiler Inspector	Build SC IR from equations, verify, emit SystemVerilog
Synthesis Dashboard	One-click Yosys synthesis to ice40/ECP5/Gowin/Xilinx, multi-target comparison, resource bars
Training Monitor	Live loss/accuracy curves via SSE, 6 surrogate gradients, per-layer spike rates
Network Canvas	Drag-and-drop populations and projections (React Flow), NIR export/import
Full Pipeline	Network → simulate → compile → synthesise in one click
Project Save/Load	Persistent workspaces as JSON, server-side storage

No other SNN framework provides a visual design-to-hardware pipeline. snnTorch has Jupyter notebooks. Brian2 has a basic GUI. Neither goes from visual network design to FPGA resource estimation.

Visual network design	Yes	Basic	No	Yes
ODE equation editor	Yes	No	No	No
Live training curves	Yes	No	TensorBoard	No
Verilog output viewer	Yes	No	No	No
FPGA synthesis	Yes	No	No	No

iverilog -o tb_lif hdl/sc_lif_neuron.v hdl/tb_sc_lif_neuron.v
vvp tb_lif

# 3. Compare results
python scripts/cosim_gen_and_check.py --check

Install Extras

Start with the base package. It installs the Python package plus numpy and scipy; it does not install PyTorch, JAX, Qiskit, PennyLane, Lava, FastAPI, or hardware toolchains.

pip install sc-neurocore              # base package: core simulation, compiler, HDL scaffold
pip install sc-neurocore[core]        # explicit base profile
pip install sc-neurocore[training]    # PyTorch-backed training
pip install sc-neurocore[nir]         # NIR import/export
pip install sc-neurocore[studio]      # local web studio
pip install sc-neurocore[bioware]     # biological closed-loop prototypes

Acceleration and research extras are intentionally opt-in:

pip install sc-neurocore[accel]       # Numba JIT experiments
pip install sc-neurocore[gpu]         # CuPy CUDA experiments
pip install sc-neurocore[jax]         # JAX-backed experiments
pip install sc-neurocore[quantum]     # research-grade Qiskit/PennyLane bridges
pip install sc-neurocore[lava]        # Lava interop experiments
pip install sc-neurocore[research]    # plotting, graph, ONNX, and torch research stack
pip install sc-neurocore[full]        # local research environment only; pulls heavy extras

See Install Profiles before using full. The default package and FPGA scaffold flow do not require those heavy extras.

For development (includes all modules and source-only research code):

pip install -e ".[dev]"               # editable install with pytest, mypy, ruff, hypothesis

Pinned dependency files for reproducible environments:

pip install -r requirements.txt       # runtime only
pip install -r requirements-dev.txt   # runtime + dev tools
