Performance-constrained voltage assignment in multiple supply voltage SoC floorplanning
ACM Transactions on Design Automation of Electronic Systems, 2009Using voltage island methodology to reduce power consumption for System-on-a-Chip (SoC) designs has become more and more popular recently. Currently this approach has been considered either in system-level architecture or postplacement stage. Since hierarchical design and reusable intellectual property (IP) are widely used, it is necessary to optimize ...

Improving Voltage Assignment by Outlier Detection and Incremental Placement
2007 44th ACM/IEEE Design Automation Conference, 2007Design for low power has become a key requirement in today's SoC design, especially for mobile applications. Multi-Vdd is an effective method to reduce both leakage and dynamic power. In a multi-Vdd design, cells of different supply voltages are often grouped into a small number of voltage islands, in order to avoid complex power supply system and ...

Technique for Transition Energy-Aware Dynamic Voltage Assignment
IEEE Transactions on Circuits and Systems II: Express Briefs, 2006It is generally accepted that dynamic voltage scaling (DVS) is one of the most effective techniques in saving energy consumption. This work addresses an important DVS problem, which is the transition energy-aware voltage assignment (TE-VA) problem. Given a schedule of tasks, the TE-VA problem is to determine the voltages to be applied to the tasks, so ...

Multi-Objective 3D Floorplanning with Integrated Voltage Assignment
ACM Transactions on Design Automation of Electronic Systems, 2017Voltage assignment is a well-known technique for circuit design, which has been applied successfully to reduce power consumption in classical 2D integrated circuits (ICs). Its usage in the context of 3D ICs has not been fully explored yet although reducing power in 3D designs is of crucial importance, for example, to tackle the ever-present challenge ...

Optimal module and voltage assignment for low-power
Proceedings of the ASP-DAC 2005. Asia and South Pacific Design Automation Conference, 2005., 2005Reducing power consumption through high-level synthesis has attracted a growing interest from researchers due to its large potential for power reduction. In this work we study functional unit binding (or module assignment) given a scheduled data flow graph under a dual-V/sub dd/ framework.

Rethinking Threshold Voltage Assignment in 3D Multicore Designs
2010 23rd International Conference on VLSI Design, 2010Due to the inherent nature of heat flow in 3D integrated circuits, stacked dies exhibit a wide range of thermal characteristics. The strong dependence of leakage with temperature and process variation plays havoc in achieving system level energy efficiency in such systems, complicating the task of power provisioning in 3D multicores.

Power controller with assigned or zero-voltage drop
Proceedings of the Institution of Electrical Engineers, 1979An experimental controller is described in which the load is supplied through a series paraformer inductance. By rapid modulation of the inductance within the supply cycle a good waveform can be supplied to the load, when the source has an impaired waveform.

Voltage Drop Aware Power Pad Assignment and Floorplanning for Multi-voltage SoC Designs
2013 International Conference on Computer-Aided Design and Computer Graphics, 2013Multi-voltage technique is an effective way of power saving in system-on-a-chip (SoC) designs. However, as the technology nodes continue to shrink, the voltage drop constraint in multiple power domains presents serious obstacles in power/ground (P/G) network design of wire-bonding package.

A New Algorithm for Simultaneous Gate Sizing and Threshold Voltage Assignment
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2009Gate sizing and threshold voltage (Vt) assignment are popular techniques for circuit timing and power optimization. Existing methods, by and large, are either sensitivity-driven heuristics or based on rounding continuous optimization solutions. Sensitivity-drive heuristics are easily trapped in local optimum and the rounding is subject to remarkable ...

2013 International Conference on Field-Programmable Technology (FPT), 2013
Embedded systems often contain many components, some with multiple Field Programmable Gate Arrays (FPGAs). Designing Printed Circuit Boards (PCBs) for these systems can be a complex process that is often tedious, error-prone, and time-intensive. Existing computer-aided design tools require designers to manually insert components and explicitly define ...
