Integrated Circuit Performance Optimization with Simulated Annealing Algorithm and Spice-pac Circuit Simulator

چکیده
The circuit design problem consists in determining acceptable parameter values (resistors, capacitors, transistor geometries . . . I which allow the circuit to meet various user given operational criteria (DC consumption, AC bandwidth, transient rise times, etc). This task is equivalent to a multidimensional and/or multi objective optimization problem: n-variables functions have to be minimized in an hyperrectangular domain: equality and/or inequality constraints can be eventually specified. We propose an efficient algorithm, based on the repeated application of SIMULATED ANNEALING to a certain number of p-variables sub problems, with p<<n. Objective functions are computed through the modular SPICE-PAC simulator, which is controled by the optimization algorithm.

DESA: a new hybrid global optimization method and its application to analog integrated circuit sizing
This paper presents a new hybrid global optimization method referred to as DESA. The algorithm exploits random sampling and the metropolis criterion from simulated annealing to perform global search. The population of points and efficient search strategy of differential evolution are used to speed up the convergence. The algorithm is easy to implement and has only a few parameters. The theoreti...

This paper presents a new optimization algorithm for automatic sizing of integrated circuits (IC) in SPICE. We refer to the new method as DESA. It is a hybrid between two very popular oprimization methods. The first one is differential evolution (DE) which is a robust population based optimization method and has received a lot of attention in the recent years. It was also sucessfully applied to...

This study aims to deal with a more realistic combined problem of project scheduling and material ordering. The goal is to minimize the total material holding and ordering costs by determining the starting time of activities along with material ordering schedules subject to some constraints. The problem is first mathematically modelled. Then a hybrid simulated annealing and genetic algorithm is...
متن کاملFit–2, an Extraction Program Based on the Spice–pac Simulation Software
Accurate and reliable simulation of a circuit behaviour cannot be obtained without adequate device models. FIT–2 is an interactive program for extraction of transistor parameters for SPICE–like circuit simulators. It is based on a circuit simulator rather than an explicit set of model equations. Several optimization methods are built into the program to provide robust as well as efficient fitti...
