TL;DR: The computer-aided design tool that finds an optimal implementation of a circuit by bottom-up approach is described, based on iterative deepening and heuristics to reduce the computation time.
Abstract: This paper treats the problems involved in the design of logic circuits based on novel processing platform. It begins with description of the ternary quantum-dot cell, an extended classic binary cell. These cells are basic building blocks of quantum-dot cellular automata. They are used to construct simple structures with inputs and output which implement some ternary logic function. These structures are employed as building blocks of larger and more complex circuits. The computer-aided design tool that finds an optimal implementation of a circuit by bottom-up approach is described. The search of a solution is based on iterative deepening. Since searching over all possible solutions is too computationally complex, heuristics are used to reduce the computation time.

TL;DR: Testability modeling has been performed for many years as discussed by the authors and has been used to assess whether a product meets a requirement to achieve a desired level of test coverage, but has little pro-active effect on making the design more testable.
Abstract: Testability modeling has been performed for many years. Unfortunately, the modeling of a design for testability is often performed after the design is complete. This limits the functional use of the testability model to determining what level of test coverage is available in the design. This information may be useful to help assess whether a product meets a requirement to achieve a desired level of test coverage, but has little pro-active effect on making the design more testable. This paper will layout the reasons for adding testability modeling to design effort and the process by which modeling can be effectively utilized to improve an electrical designs' testability. It will cover some of the assumptions that must be made initially about testability at a programs onset, the phases in a programs lifecycle that testability modeling should be performed, the level of detail that a testability model should contain, the review and other processes that should be used to validate the model and determine if design modification/improvements should be performed, as well as the way testability should be incorporated into a program's overall test strategy. The information related in this document is based upon the personal experience of the author as the company he works for attempts to better utilize new and existing design tools and processes to improve the manufacturability of its designs and reduce the overall cost of its products in an ever more challenging defense acquisition environment.

TL;DR: STARS⋆CELL, a PC-based simulator for the design and evaluation of flexible manufacturing cell (FMC) flow line systems, and the effects of various design variables on cell performance.
Abstract: This paper discusses STARsCELL, a PC-based simulator for the design and evaluation of flexible manufacturing cell (FMC) flow line systems. As a design tool, STARsCELL aids in determining the ideal number of machines, number and assignment of operators, and the size of inter-workstation buffers. The menu-driven simulator also assists in evaluating the impact on cell performance of Just-in-Time (JIT) factors, changes in product mix and demands, and different user-specified job input sequences. The paper provides numerical results for a gear workcell example to illustrate the effects of various design variables on cell performance. A brief discussion of the development, applications, advantages, and limitations of STARsCELL is also presented.

TL;DR: This paper describes a process for creating a design tool, which is based in constructivism, to help novices in designing virtual environment interactions, however it can be generalized to other design domains.
Abstract: This paper describes a process for creating a design tool, which is based in constructivism. The process is described for the creation of a tool to help novices in designing virtual environment interactions, however it can be generalized to other design domains. The process consists of four steps: first constructivist values of atomic simplicity, multiplicity, exploration, control and reflection are distilled. Next, expert practices are researched and reframed in terms of the constructivist values. Thirdly, novice processes are examined and understood in constructivist terms. Lastly, prototypes are created and shown to target users. These steps are iterated until the designed tool is satisfactory.
