Parallel processing has recently become an extremely attractive and cost effective way of achieving orders of magnitude performance improvements in VLSI CAD applications. In this paper, we propose parallel algorithms to speed up the VLSI circuit extraction task. Given a VLSI layout as input, the problem of circuit extraction consists of determining the circuit connectivity and estimating the va...

-In this paper, techniques are described which demonstrate how a highly detailed internal transformer model can be obtained systematically with Matlab and how it can be prepared for subsequent transient analysis. The input of such a model will mainly be the description of the cross section of a single transformer leg, including all turns and windings. From the input data a three phase equivalen...

In this paper, we present an approach and a visual tool, called HWrap (Handle Based Wrapper), for creating web wrappers to extract data records from web pages. In our approach, we mainly rely on the visible page content to identify data regions on a web page. In our extraction algorithm, we inspired by the way a human user scans the page content for specific data. In particular, we use text fea...

An interface to symbolic circuit analysis has been developed for a SPICE-like circuit simulator in order to integrate numerical simulation with an existing program for symbolic circuit analysis. In effect, both numerical and symbolic analyses use the same internal representation of circuits which makes the two approaches truly complementary. This integrated simulation capability is used in simu...

The design of a VLSI circuit consists of a description of the circuit in terms of its components and subcomponents at various levels of detail To verify that the layout of a VLSI circuit conforms to its design one needs to work back wards from the lowest level description of the circuit and recognize the higher level components it constitutes This paper is concerned with the application of logi...

The paper presents an improved equivalent circuit parameters extraction method for the dumbbell-shaped defected ground structure (DGS). The new extraction parameters equations are obtained in closed-form expressions, which contain S11 and S21. The DGS unit with center frequency of 5 GHz is designed and fabricated on a TLX substrate with thickness of 1 mm and dielectric constant of 2.55. The cir...

The novel method is to optimize coarse-grained floating point units (FPUs) in a hybrid FPGA by employing common sub graph extraction to determine the number of floating point adders / subtracters (FAs), multipliers (FMs) and word blocks (WBs) in the FPUs. Single precision FP adders / subtracters (FAs) and FP multipliers (FMs), with normalization are generated using standard cell library design ...
