MLP simlator (+NeuroSim) V2.0

The MLP+NeuroSim framework was developed by Prof. Shimeng Yu's group (Arizona State University). The model is made publicly available on a non-commercial basis. Copyright of the model is maintained by the developers, and the model is distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International Public License

This is the released version 2.0 (May 1st, 2018) for the tool. Besides analog eNVM (in MLP simulator V1.0), this version also includes some new devices: SRAM, digital eNVM (RRAM, PCM and STT-MRAM) and FeFET, an optimized weight update scheme is introduced to reduce latency and energy in training.

For algorithm weights range extended from (0, 1) to (-1, 1) with more training algorithms (such as momentum method, Adagrad, RMSprop, and Adam), and digital eNVMs (e.g. STT-MRAM) based synaptic array with parallel read-out fashion, please go to released version 3.0 (Mar. 1st, 2019) MLP simulator (+NeuroSim) V3.0.
