An Open-source tool for modeling 2D/3D, SLC/MLC memories


We have just released version 2 of DESTINY, which can model:
* (2D/3D) SRAM and eDRAM
* (2D, SLC/MLC) SOT-RAM, Flash, DWM

(SLC/MLC = single/multi-level cell, DWM = domain wall memory, SOT-RAM = spin orbit torque RAM, STTRAM = spin transfer torque RAM, PCM = phase change memory)

Features of DESTINY:
* Can model 22nm to 180nm technology nodes
* It can model both conventional and emerging memories
* Validated against several commercial prototypes
* A comprehensive modeling tool

In its purpose, DESTINY is similar to CACTI, CACTI-3DD or NVSim. The source code is available here:
sparsh_mittal / destiny_v2 — Bitbucket

The journal paper which describes DESTINY in full detail is attached.

Great news and thanks for sharing! The Open Source Silicon ecosystem keeps growing. I just got back from ORConf last week and one of the highlights there was to see how much advancement has been made for Open Source ASIC development. Both when it comes to tools, licenses and fabrication. Perhaps you would be interested in presenting your work at ORConf next year?
