Dynamic Voltage Scaling(DVS) and Dynamic Power Management(DPM) are two major techniques for reducing energy consumption in computer systems today. In this paper, we will propose a model that can capture the key characteristics of power management in today's advance computer systems. In this model, a processor in active mode can run at a number of speeds and each has a different energy consumption...
Power consumption has become a crucial problem in modern circuit design. Multiple supply voltage (MSV) design is introduced to provide higher flexibility in controlling the power and performance tradeoff. One important requirement of MSV design is that timing constraints of the circuit must be satisfied after voltage assignment of the cells. In this article, we develop two algorithms to solve the...
Clock network construction is one key problem in high performance VLSI design. Reducing the clock skew variation is one of the most important objectives during clock network synthesis. Local clock skew (LCS) is the clock skew between any two sinks with distance less than or equal to a given threshold. It is defined in the ISPD 2010 High Performance Clock Network Synthesis Contest, and it is a novel...
In this paper, we present an efficient method to solve the obstacle-avoiding rectilinear Steiner tree problem optimally. Our work is developed based on the GeoSteiner approach, modified and extended to allow rectilinear blockages in the routing region. We extended the proofs on the possible topologies of full Steiner tree (FST) to allow blockages, where FST is the basic concept used in GeoSteiner...
