VELVET is a very-low voltage system-on-chip consisting of an open-source RISC-V processor and a deep neural network accelerator designed with cross-layer reliability techniques to prevent low-voltage processor failures. This heterogeneous system employs circuit, system and application level resiliency techniques to enable reliable low-voltage operation.

The thermal performance of Processing in Memory(PiM) 3D IC's  are of critical importance. An emphasis is given on developing a robust thermal modelling network that investigates into novel cooling methods, such as dynamic flow rate microchannels based on the location of hotspots. 3D IC thermal management have been addressed by dynamic thermal management method which controls the direction and magnitude of microfluidic flows in the thermal chamber by multiplexing inlets and outlets.

Our goal is to increase chips’ endurance. Old/used electronics can regain their functionality with either passive or active recovery. Developing an efficient method on recovery is crucial for practicality. Chips need to do exercise.

Unwanted access to private intellectual property and circuit designs during manufacturing and distribution has led to a serious need to establish protective measures against malicious attacks. We make use of electronic printing, obfuscation techniques, and design for security to build defense features that protect hardware against malicious modification, reverse engineering, and vulnerability exploitation.

The idea of an end to end asynchronous system is of great interest for ultra low power applications where there is a clear trade-off between power and accuracy. Stochastic computing when implemented asynchronously proves to be an innovative solution towards lesser hardware and silicon footprint.

The compact size, high stability and ultra-low depinning current density make skyrmion a potential candidate for future memory technology. Skyrmion can be used to design conservative logic system, stochastic computing. The goal of this project is to design energy efficient memory and logic circuits and systems to replace CMOS based technologies by exploiting the non-volatility of highly stable magnetic skyrmion.
