چکیده
his article presents a comprehensive analysis of the thermal effects in advanced high-performance interconnect systems arising due to self-heating under various circuit conditions, including electrostatic discharge (ESD). Technology (Cu, low-k, etc.) and scaling effects on the thermal characteristics of the interconnects, and on their electromigration (EM) reliability, have been analyzed simultaneously, which have important implications for providing robust and aggressive deep sub-micron (DSM) interconnect design guidelines. The analysis takes into account the effects of increasing interconnect (Cu) resistivity with decreasing line dimensions and the effect of a finite barrier metal thickness. Furthermore, the impact of these thermal effects on the design (driver sizing) and optimization of the in-

A global wiring paradigm for deep submicron design
Global interconnect is commonly regarded as a key potential bottleneck to the advancing performance of high-speed integrated circuits. Our previous work has suggested that local interconnect effects can be managed through a deep submicron design hierarchy that uses 50 000 to 100 000 gate modules as primitive building blocks. The primary goal of this paper is to examine global interconnect effec...
متن کاملBehavioral Modeling and Simulation of Semiconductor Devices and Circuits Using VHDL-AMS
During the past few years, a lot of work has been done on behavioral models and simulation tools. But a need for modeling strategy still remains. The VHDL-AMS language supports the description of analog electronic circuits using Ordinary Differential Algebraic Equations (ODAEs), in addition to its support for describing discrete-event systems. For VHDL-AMS to be useful to the analog design ...
متن کاملHarmony: static noise analysis of deep submicron digital integrated circuits
As technology scales into the deep submicron regime, noise immunity is becoming a metric of comparable importance to area, timing, and power for the analysis and design of very large scale integrated (VLSI) systems. A metric for noise immunity is defined, and a static noise analysis methodology based on this noise-stability metric is introduced to demonstrate how noise can be analyzed systemati...
متن کاملDesign Challenges in Subthreshold Interconnect Circuits
As technology advances to giga-scale integration level, global interconnect resource becomes increasingly valuable in a VLSI chip. This is due to the exponential growth of the total number of interconnects/wires as the feature size of MOS transistors decreases in scaled deep submicron CMOS technologies. Interconnect length, however, has not scaled down with feature size and remains long relativ...
