There has been much discussion about environmental issues in manufacturing and the design of new products. The challenge is to integrate environmental considerations into the design and manufacturing operations so that it becomes part of the normal operating procedures. This paper is a description of a framework for integration of environmental considerations into design and manufacturing operations. The paper first describes the current state of the art for product design, but does not preclude the use of the same techniques for processdesign as well. design for environment is then introduced by comparing DFE to design for manufacturability. Environmental life cycle assessment is introduced next as the most popular method for assessing the environmental impact of a product or process along with a short discussion on measuring design merit. Finally all of these subjects are brought together in a framework for implementing design for environment into process and product design.

The paper presents several design issues associated with the implementation of a three dimensional optically interconnected parallel processing system. A technique for improving bit error rate in low power multistage networks is presented. Error detection codes are transmitted along with message data to guarantee the integrity of the data during each optical hop. To realize three dimensional through silicon wafer interconnect, thin film emitters and detectors operating at a wavelength of 1.3 /spl mu/m (to which silicon is transparent) will be bonded to the silicon circuitry. A transfer diaphragm process is used to realize this integration; this process has been used to demonstrate the basic concept: a single silicon circuit has been integrated with both a thin film emitter and detector operating at 1.3 /spl mu/m wavelength (K.H. Calhoun et al., 1993). We utilize one possible integration scenario to illustrate the trade offs associated with a system of this type, which includes device design, circuit design, and issues which include manufacturability, alignment tolerance, crosstalk, and power dissipation.

An integrated interconnect modelling system, SIMS, is developed with parametrized modeling of interconnect and an interface with schematic capture and editor. SIMS automatically drives numerical interconnect simulation as directed by technology engineers, creates a polynomial model library for interconnect parasitics, generates a netlist including the SPICE model for the interconnect structure, automatically drives circuit simulations and displays the simulation results through an advanced GUI. VLSI design with SIMS makes it possible to consider parasitic effects fast and accurately, which becomes more important in deep submicron circuit design. With this capability, circuit design with optimized interconnect layout can be achieved. Ultimately, the integrated system helps to reduce the cost of technology development and the time to market by building up the concept of design for manufacturability.

A low power multiplication algorithm and its VLSI architecture using a mixed number representation is proposed. The reduced switching activity and low power dissipation are achieved through the Sign-Magnitude (SM) notation for the multiplicand and through a novel design of the Redundant Binary (RB) adder and Booth decoder. The high speed operation is achieved through the Carry-Propagation-Free (CPF) accumulation of the Partial Products (PP) by using the RB notation. Analysis showed that the switching activity in the PP generation process can be reduced on average by 90%. Compared to the same type of multipliers, the proposed design dissipates much less power and is 18% faster on average.
