YIELD AND VARIABILITY OPTIMIZATION OF INTEGRATED CIRCUITS

Opis produktu

Traditionally Computer Aided Design (CAD) tools have been used to create the nominal design of an integrated circuit (IC) such that the circuit nominal response meets the desired performance specifications. In reality however due to the disturbances ofthe IC manufacturing process the actual performancesof the mass produced chips are different than those for the nominal design. Even if the manufacturing process were tightly controlled so that there were little variations across the chips manufactured the environmentalchanges (e. g. those oftemperature supply voltages etc. ) would alsomakethe circuit performances vary during the circuit life span. Processrelated performance variations may lead to low manufacturing yield and unacceptable product quality. For these reasons statistical circuit design techniques are required to design the circuit parameters taking the statistical process variations into account. This book deals with some theoretical and practical aspects of IC statistical design and emphasizes how they differ from those for discrete circuits. It de scribes a spectrum of different statistical design problems such as parametric yield optimization generalized ontarget design variability minimization per formance tunning and worstcase design. The main emphasis of the presen tation is placed on the principles and practical solutions for performance vari ability minimization. It is hoped that the book may serve as an introductory reference material for various groups of IC designers and the methodologies described will help them enhance the circuit quality and manufacturability.
