An original approach is presented to the timedependent thermal modelling of complex 3-dimensional electronic systems, from metallised power FETs and MMICs, though MCMs, up to circuit board level. This method o ers a powerful alternative to conventional numerical thermal simulation techniques. In contrast to semi-analytical Fourier approaches involving DFT-FFT, the method is based on explicit, f...

A lumped-element circuit is proposed to model a coplanar waveguide (CPW) interdigital capacitor (IDC). Closed-form expressions suitable for CAD purposes are given for each element in the circuit. The obtained results for the series capacitance are in good agreement with those available in the literature. In addition, the scattering parameters obtained from the circuit model are compared with th...

(ABSTRACT) This work presents the modeling and analysis of EMI and thermal performance for switch power supply by using the CAD tools. The methodology and design guidelines are developed. By using a boost PFC circuit as an example, an equivalent circuit model is built for EMI noise prediction and analysis. The parasitic elements of circuit layout and components are extracted analytically or by ...

In the near future, the Federal Circuit will grapple with the subject matter eligibility, under § 101 of the Patent Act, of Computer Aided Design (CAD) files—software that powers 3D printers and contains the design prototype a printer additively manufactures. Where the Federal Circuit comes down on whether or not CAD files are patent-eligible will have serious innovation and economic policy imp...

This paper presents a system-level methodology (AAA) for signal and image processing algorithms onto circuit architecture. This AAA (Algorithm Architecture Adequation) methodology is added and implemented in an existing software dedicated to the fast prototyping and optimization of real-time embedded algorithms onto multicomponent architectures. The resulting tool, called SynDExIC, is a free gr...

Hardware Trojans inserted by malicious foundries during integrated circuit manufacturing have received substantial attention in recent years. In this paper, we focus on a different type of hardware Trojan threats: attacks in the early steps of design process. We show that third-party intellectual property cores and CAD tools constitute realistic attack surfaces and that even system specificatio...

Dynamic Circuit Specialization (DCS) is a new FPGA CAD tool flow that uses Run-Time Reconfiguration to automatically specialize the FPGA configuration for a whole range of specific data values. DCS implementations are a factor 5 faster and need a factor 8 less luts compared to conventional implementations. We propose a novel routing algorithm for reconfigurable routing, called the Connection ro...

This paper presents an algorithm for fast large-change sensitivity computation for approximate symbolic analysis. The sensitivity is used for identifying negligible elements of circuit model that can be removed in order to simplify symbolic solution. The method is based on combination of the Sherman-Morison formula and sparse matrix techniques. Effectiveness of the method was tested on several ...

A CAD tool, MOSGRAD, that can be used to simulate the effects of distributed two-dimensional systematic and random variations in device parameters on the performance of matchingcritical circuits has been developed. In addition to applications for layouts with conventional rectangular transistors, this tool can predict the performance of non-conventional circuit structures in which multiple drai...
