Über dieses Buch

This book describes new, fuzzy logic-based mathematical apparatus, which enable readers to work with continuous variables, while implementing whole circuit simulations with speed, similar to gate-level simulators and accuracy, similar to circuit-level simulators. The author demonstrates newly developed principles of digital integrated circuit simulation and optimization that take into consideration various external and internal destabilizing factors, influencing the operation of digital ICs. The discussion includes factors including radiation, ambient temperature, electromagnetic fields, and climatic conditions, as well as non-ideality of interconnects and power rails.

Chapter 1. General Issues of Gate-Level Simulation and Optimization of Digital Circuits with Consideration of Destabilizing Factors

Abstract
Principles of constructing systems for simulating and optimizing digital circuits with consideration of destabilizing factors (DF) are described, including principles of considering the influence of DF on the functioning of digital circuits, construction of models of logic elements, determination of the influence of DF on logic elements, organization of the system for simulating and optimizing digital circuits with consideration of DF. The effectiveness and prospects of this class of systems for simulating and optimizing digital circuits are shown.

Chapter 2. Models of Logical Elements for DF Consideration

Abstract
A logical model of a digital element is described for taking into account the influence of DF, providing accuracy of simulation results close to the circuit analysis and slightly less than logical analysis of the speed of calculations on the account of the operation of continuous variables, the use of the corresponding rules for calculating logical functions and interpretations of the generalized variable of considered DFs in the simulation process.

Chapter 3. Models for Determining the Influence of DF

Abstract
A number of semiempirical models for determining the influence of various external (total radiation dose, ambient temperature, supply voltage, slope of the input signal, amplitude of the input signal, number of loads) and internal (interconnects, power buses) DFs on the parameters of models of logical elements for TTL, ECL and CMOS technologies are described.

Chapter 4. Algorithmic Implementation of the Automated System of Gate-Level Simulation of Digital Circuits with Consideration of DF

Abstract
An algorithm of logic simulation of digital circuits with consideration of destabilizing factors, preserving the advantages of well-known logic simulation algorithms and at the same time, providing consideration of all the features of the developed model of considering effects - the operation of signals with arbitrary amplitude and duration, change of timing parameters during simulation, etc. is described. Algorithms of mixed-mode simulation with consideration of destabilizing factors are also described, which ensure maximum independence of electrical and logic simulation.

Chapter 5. Optimization of Digital Circuits with Consideration of DF

Abstract
An algorithm for optimizing the critical timing paths of digital circuits, taking into account the influence of destabilizing factors with the minimal growth of power consumption by the circuit is described. The algorithm is tested on digital circuits of the ISCAS89 series. An algorithm to solve the problem of reducing the level of power consumption of digital circuits, taking into account the influence of destabilizing factors at the expense of the use of the speed margin in the design options of digital circuits is also described.
