Multi-voltage floorplan design with optimal voltage assignment

Proceedings of the 2009 international symposium on Physical design, 2009
In this paper, we study the multiple voltage assignment (MVA) problem under timing constraints in floorplanning, which is generally an NP-hard problem. We will present an effective value-oriented branch-and-bound based algorithm to solve it optimally in a reasonable amount of time.

Timing-constrained and voltage-island-aware voltage assignment

2006 43rd ACM/IEEE Design Automation Conference, 2006
Multi-Vdd is an effective method to reduce both leakage and dynamic power. A key challenge in a multi-Vdd design is to limit the design cost and the demand for level shifters. This can be tackled by grouping cells of different supply voltages into a small number of voltage islands.

Incremental Improvement of Voltage Assignment

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2009
Design for low power has become a key requirement in today's System-on-a-Chip design, particularly for mobile applications. Multi-Vdd (MSV) is an effective method to reduce both leakage and dynamic powers. In a MSV design, cells of different supply voltages are often grouped into a small number of voltage islands, in order to avoid complex power-supply

Generic algorithm based voltage Islands-Aware Multiple Voltage Assignment

2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010
Power consumption has become one of most serious challenges for SoC design. Among the various methods, Multiple Supply Voltage (MSV) is an effective method for power reduction. In this paper, Genetic Algorithm (GA) is used to optimize the Voltage Islands-Aware Multiple Voltage Assignment (VIAMVA).

Multiple voltage assignment based on PSO

Proceedings of 2011 International Conference on Computer Science and Network Technology, 2011
today the power optimization has become a crucial concern in modern IC design. Multiple supply voltage (MSV) is efficient way to achieve low power. Most of the researches are carried out in the simulated annealing scheme. In this paper, a novel particle swarm optimization approach was proposed for multiple voltage islands generations at the post ...

Postplacement voltage assignment under performance constraints

ACM Transactions on Design Automation of Electronic Systems, 2008
Multi-Vdd is an effective method to reduce both leakage and dynamic power. A key challenge in a multi-Vdd design is to control the complexity of the power-supply system and limit the demand for level shifters. This can be tackled by grouping cells of different supply voltages into a small number of voltage islands.
