Sparse linear systems are found in a variety of scientific and engineering problems. In VLSI CAD tools, DC circuit analysis creates large, sparse systems represented by matrices and vectors. The algorithms designed to solve these systems are known to be quite time consuming and many previous attempts have been made to parallelize them. Graphics cards have evolved from specialized devices into m...

Electrical model of a magnetic tunnel junction is developed in Verilog-A language, which can use CAD systems to design an integrated circuit spintronics devices. In order check the correct operation verification tests were created and carried out Cadence ADE. Each test corresponds operating mode junction: switching, generation, rectification. Thus, be used simulate hybrid circuits comprising CM...

This dissertation is in the area of Computer-Aided Design (CAD) of digital Integrated Circuits (ICs). Today’s digital ICs, such as microprocessors, memories, digital signal processors (DSPs), etc., range from a few thousands to billions of logic gates, flip-flops, and other components, packed in a few millimeters of area. The creation of such highly complex systems would not be possible without...

In this study, properties usage purposes nickel-cadmium (Nickel-C...

The Odyssey CAD Framework is a comprehensive framework intended to provide services for tool integration, data management, task management, and design process management. This report introduces dynamically defined flows: tool independent flows that are built up on demand, by designers. Dynamically defined flows support many framework services and several design approaches, without some of the d...

This paper reviews the current state of the art in circuit optimization, emphasizing techniques suitable for modern microwave CAD. It is directed at the solution of realistic design and modeling problems, addressing such concepts as physical tolerances and model uncertainties. A unified hierarchical treatment of circuit models forms the basis of the presentation. It exposes tolerance phenomena ...

Circuit simulation has proven to be one of the most important computer aided design (CAD) methods for verification and analysis of, integrated circuit designs. A popular approach to modeling circuits for simulation purposes is to use a hardware description language such as VHDL. VHDL has had a tremendous impact in fostering and accelerating CAD systems development in the digital arena. Similar ...

-In this paper, a unified theory for frequency-domain simulation and sensitivity analysis of linear and nonlinear circuits is presented. An elegant derivation expands the harmonic balance technique from nonlinear simulation to nonlinear adjoint sensitivity analysis. This provides an efficient tool for the otherwise expensive but essential gradient calculations in design optimization. The hierar...

A Hierarchical Description Language and Packing Algorithm for Heterogenous FPGAs Jason Luu Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2010 The complexity of Field-Programmable Gate Array (FPGAs) logic blocks have undergone constant evolution to the point where both the basic soft logic blocks that implement combinational logic and ...

The introductory VLSI design course at the University of Michigan has been ooered for over 10 years. More recently, it has been reorganized around a microprocessor design project. This paper describes the course philosophy and content, and the baseline project from which class projects begin. The introductory VLSI course, EECS427, teaches mask-level layout and integrated circuit design veriicat...
