A new layout design system for multichip modules (MCMs) consisting of three components is described. It includes a k-way partitioning approach, an algorithm for pin assignment, and a placement package. For partitioning, we propose an analytical technique combined with a problem-specific multi-way ratio cut method. This method considers fixed module-level pad positions and assigns the cells to regularly arranged chips on the MCM substrate. In the subsequent pin assignment step the chip-level pads resulting from cut nets are positioned on the chip borders. Pin assignment is performed by an efficient algorithm, which profits from the cell coordinates generated by the analytical technique. Global and final placement for each chip is computed by the state-of-the-art placement tools GORDIANL and DOMINO. For the first time, results for MCM layout designs of benchmark circuits with up to 100,000 cells are presented. They show a small number of required chip-level pads, which is the most restricted resource in MCM design, and short total wire lengths.

Abstract This paper describes a new approach to an automated layout design system for industrial plant piping. The routing system, which is the main part of this layout system, is composed of three steps, according to the practical layout design process. By dividing the layout design into the optimal routing phase (Step 1, Step 2) and the arrangement phase (Step 3), it is possible to design without depending on the routing order, and with small computer memory storage capacities. The optimal route is obtained by using the routing algorithm and heuristic search, based on expert knowledge. The arrangements are made by applying the enumeration method, taking the strong and weak constraints into account.

Effective Implementation

In accordance with the increased awareness of resource depletion and environmental pollution, the importance of eco-friendly disposal and recycling of vehicles as a potentially valuable resource is emphasized; in particular, this is important as automobile production and demand continues steadily. In this paper, a systematic dismantling system is proposed to minimize the quantity of ASR by dismantling End-of-Life Vehicles (ELVs) rationally and efficiently. An adaptive layout design system is also provided to aid for the effective implementation of the proposed dismantling system to industrial applications. The proposed dismantling system is based on eco-friendly dismantling and improves not only the recyclability of ELVs, but also the efficiency of the dismantling operations. The adaptive layout design system is a software tool, which allows a layout of a dismantling plant according to the specific requirements of the customers, and estimates the overall figures and capacity of an intended plant by simulation of the dismantling process. This interactive design system can be useful for testing alternative layouts of a dismantling plant customized to meet particular recycling needs.

In order to consider the psychological cognitive characteristics affecting operating comfort and realize the automatic layout design, cognitive ergonomics and GA-ACA (genetic algorithm and ant colony algorithm) were introduced into the layout design of human-machine interaction interface. First, from the perspective of cognitive psychology, according to the information processing process, the cognitive model of human-machine interaction interface was established. Then, the human cognitive characteristics were analyzed, and the layout principles of human-machine interaction interface were summarized as the constraints in layout design. Again, the expression form of fitness function, pheromone, and heuristic information for the layout optimization of cabin was studied. The layout design model of human-machine interaction interface was established based on GA-ACA. At last, a layout design system was developed based on this model. For validation, the human-machine interaction interface layout design of drilling rig control room was taken as an example, and the optimization result showed the feasibility and effectiveness of the proposed method.
