TL;DR: RetroFab is an end-to-end design and fabrication environment that allows non-experts to retrofit physical interfaces and demonstrates the versatility and novel opportunities of the approach by retrofitting five domestic objects and exploring their use cases.
Abstract: We present RetroFab, an end-to-end design and fabrication environment that allows non-experts to retrofit physical interfaces Our approach allows for changing the layout and behavior of physical interfaces Unlike customizing software interfaces, physical interfaces are often challenging to adapt because of their rigidity With RetroFab, a new physical interface is designed that serves as a proxy interface for the legacy controls that are now operated by actuators RetroFab makes this concept of retrofitting devices available to non-experts by automatically generating an enclosure structure from an annotated 3D scan This enclosure structure holds together actuators, sensors as well as components for the redesigned interface To allow retrofitting a wide variety of legacy devices, the RetroFab design tool comes with a toolkit of 12 components We demonstrate the versatility and novel opportunities of our approach by retrofitting five domestic objects and exploring their use cases Preliminary user feedback reports on the experience of retrofitting devices with RetroFab

TL;DR: This work develops an RRAM SPICE model that can capture all the essential device characteristics such as stochastic switching behaviors, multi-level cell, switching voltage variations, and resistance distributions and provides solutions for system optimization that capitalize on device/circuit interaction.
Abstract: Resistive switching random access memory (RRAM) is a leading candidate for next-generation nonvolatile and storage-class memories and monolithic integration of logic with memory interleaved in multiple layers. To meet the increasing need for device-circuit-system co-design and optimization for applications from digital memory systems to brain-inspired computing systems, a SPICE model of RRAM that can reproduce essential device physics in a circuit simulation environment is required. In this work, we develop an RRAM SPICE model that can capture all the essential device characteristics such as stochastic switching behaviors, multi-level cell, switching voltage variations, and resistance distributions. The model is verified and calibrated by a variety of electrical measurements on ~10 nm RRAMs. The model is applied to explore a wide range of applications including: 1) variation-aware design; 2) reliability-emphasized design; 3) speed-power assessment; 4) array architecture optimization; and 5) neuromorphic computing. This experimentally verified design tool not only enables system design that utilizes the complete suite of RRAM device features, but also provides solutions for system optimization that capitalize on device/circuit interaction.

31 Jan 2007TL;DR: In this paper, the authors provide models of corresponding components, where the models contain constraints, such as at least one component is composed of at least another component, and the models are input into a design tool.
Abstract: To configure a system, models of corresponding components are provided, where the models contain constraints. The models specify that at least one of the components is composed of at least another one of the components. The models are input into a design tool. The design tool generates a configuration of the system that includes the components, wherein the generated configuration satisfies the constraints contained in the models.
