Abstract: This paper presents a spiking neural network (SNN) accelerator made using fully open-source EDA tools, process design kit (PDK), and memory macros synthesized using Open- RAM. The chip is taped out in the 130 nm SkyWater process and integrates over 1 million synaptic weights, and offers a reprogrammable architecture. It operates at a clock speed of 40 MHz, a supply of 1.8 V, uses a PicoRV32 core for control, and occupies an area of 33.3 mm2. The throughput of the accelerator is 48,262 images per second with a wallclock time of 20.72 μs, at 56.8 GOPS/W. The spiking neurons use hysteresis to provide an adaptive threshold (i.e., a Schmitt trigger) which can reduce state instability. This results in high performing SNNs across a range of benchmarks that remain competitive with state-of-the-art, full precision SNNs.

The design is open sourced and available online: https://github.com/sfmth/OpenSpike

About the conference:
EDISON 22 follows a series of conferences formerly named Hot Carriers in Semiconductors and since 2009 running under the name EDISON. It is dedicated to the latest progress in the field of fundamental physics and applications of nonequilibrium classical and quantum carrier dynamics in semiconductors, optoelectronic devices and nanostructures. Main topics of the conference are:

- Nonequilibrium electrical and thermal transport in bulk, nanostructures and devices
- Terahertz phenomena in semiconductor materials and devices
- Mesoscopic phenomena in nanostructures
- Electrical and optical properties of 2D materials and their heterostructures
- Carrier dynamics and ultra-fast optical phenomena
- Coherent carrier dynamics for quantum technologies
- Semiconductor-based spintronics
- Electronic properties of topological materials
- Carrier dynamics in organic materials
- Charge dynamics in energy conversion and energy harvesting processes
- Fluctuations and noise in nonequilibrium carrier dynamics
- Interaction of charges with plasmonic, phononic and mechanical excitations
