    Special-purpose hardware architectures have been recently proposed for solving a number of increasingly complex design automation problems. This paper proposes a class of two-dimensional SIMD array processors--the IAP architectures for implementation of grid routing algorithms. The major advantages of the IAP machines are, completely modular designs which are not pin-limited regardless of array si... View full abstract»

    In order to reduce the design time of digital filter bank circuits, a design system has been developed. The software consists of the filter compiler which converts high level filter descriptions to hardware descriptions and the layout generator which converts the hardware descriptions to a layout file. To verify the algorithms before fabrication, a test system is employed. The development time of ... View full abstract»

    Multiple-valued logics have long been used, often in intuitive fashion, for simulating transients, errors, unknown states, variable-strength signals, etc., in binary digital circuits. This paper presents a rigorous algebraic method for analyzing such logics, and for systematically constructing new ones. Starting with a basis such as 2-valued Boolean algebra, new algebras suitable for a broad range... View full abstract»

    A new (AlGa)As/GaAs MODFET integrated circuit simulator is described. Our simulator is a customized version of SPICE incorporating the extended charge control model for MODFET's and the velocity saturation model for ungated FET's used as the load devices. Comparison of our simulator results with the measured data show good agreement for both dc and transient responses. We also propose a set of ana... View full abstract»

    A standard form is presented for describing device characteristics in VLSI's. It serves as a standard interchange form for device characteristics between various design tools for VLSI's. The form is designed such that any relevant characteristic as a circuit component can be described. It also makes it possible to process an enormous amount of device data efficiently. A newly developed CAD system,... View full abstract»

    This paper describes the salient features of CAMP, a Computer Aided Minimization Procedure for single Boolean functions. The procedure is a divide and conquer algorithm, in which the essential prime implicants are first found, and then the best cover among the selective prime implicants are chosen. A significant feature of the algorithm is that the selection of the most suitable selective prime im... View full abstract»

    A new algorithm that produces a sequence of closed-form upper and lower bounds on the response of a very general class of linear RC networks is presented in this paper. The bounds approach arbitrarily close to the actual response by using a successive relaxation method. Since the accuracy of the final bounds can be improved through additional computation, the algorithm is more flexible than previo... View full abstract»

    For custom integrated circuit design, the use of a reliable device model parameter set as input for the circuit simulator is very important. The curve fitting algorithm in our parameter extraction program SIMPAR is based on a modified Marquardt fitting routine for nonlinear least squares. Classical parameter extraction programs rely only on the minimization of the relative current deviation. But, ... View full abstract»

    An approach to statistical design centering (SDC) based on a simple generalization of the production yield concept is introduced, leading to a new figure of merit called the "income index." The measure can be considered as a simple model of the manufacturer's income or as a parameter characterizing the average quality of the manufacturing process. The income index takes into account the "price" (o... View full abstract»
