Power has become one of the most important paradigms of design convergence for multi gigahertz communication systems such as optical data links, wireless products, microprocessor & ASIC/SOC designs. POWER consumption has become a bottleneck in microprocessor design. The core of a microprocessor, which includes the largest power density on the microprocessor. In an effort to reduce the power con...

Min-k-cut is the problem of partitioning vertices of a given graph or hypergraph into k subsets such that the total weight of edges or hyperedges crossing different subsets is minimized. For the capacitated min-k-cut problem, each edge has a nonnegative weight, and each subset has a possibly different capacity that imposes an upper bound on its size. The objective is to find a partition that mi...

PUNCH, the Purdue University Network Computing Hubs, is an infrastructure for network-based VLSI CAD and TCAD that allows users to access and run existing software tools via standard world-wide web browsers. Tools do not have to be written in any particular language, and access to source-code is not required. The PUNCH infrastructure is geographically distributed, but this is transparent to use...

3D Circuits are one of the most promising technologies for reducing wire lengths [1] and improving circuit power [2] and timing [3] for future high performance designs. On a 3D VLSI Circuit, tiers of active area are stacked, providing higher integration density, shrinking the distances between the cells and reducing wire lengths as a consequence. In order to take full benefit of the technology,...

Low power design is one of the primary goals for any integrated circuits. Very Large-Scale Integration (VLSI) a kind Integrated Circuit (IC) that consists hundreds and transistor connection into small chip. The communication computer applications have grown very faster in past decade due to development VLSI circuit as microcontroller microprocessors. However, still research on are moving toward...

A knowledge-based approach is suggested to assist a designer in the increasingly complex task of generating VLSI-chips from abstract, high-level specifications of the system. The complexity of designing VLSI-circuits has reached a level where computer-based assistance has become indispensable. Not all of the design tasks allow for algorithmic solutions. AI techniques can be used, in order to su...

The yield of a VLSI chip depends, among other factors, on the sensitivity of the chip to defects occurring during the fabrication process. To predict this sensitivity, one usually needs to compute the so-called critical area (A c) which reeects how many and how large the defects must be in order to result in a circuit failure. The main computational problem in yield estimation is to calculate A...
