The purpose of CBSD(Component Based Software Development) if to develop software using a reuse component and components assembly. The reused components have to be adapter for satisfaction of requirement specification. This paper represents a component adaption method which reuse previously developed component or legacy system, using an adaptation component called by TA(Transaction Adaptor). The adaptation using TA transmits XML data that is translated into stream type, from a client to on host system. And we introduce RS(Rule Server) which gets some Information from XML data for application program development. Through the Interaction of TA and RS, we can improve effectiveness of component development and maintenance and we can reuse legacy system.

In this paper we designed the motor control IP Core and evaluate its quality from the viewpoint of IP reuse. The most attractive merit of this methodology, so called IP-based hardware design, is hardware reuse. Although various vendors designed hardware with the same specification and got the same functional results, all that IPs is not the same quality in the reuse aspect. As tremendous calls for SoC have been increased, associated research about IP quality standard, VSIA(Virtual Socket Interface Alliance) and STARC(Semiconductor Technology Academic Research Center), has been doing best to make the IP quality evaluation system. And they made what conforms to objective IP design standard. We suggest the methodology to evaluate our own designed motor control IP quality with this standard. To attain our goal, we designed motor control IP that could control the motor velocity and position with feedback compensation algorithm. This controller has some IP blocks : digital filter, quadrature decoder, position counter, motion compensator, and PWM generator. Each block's functionality was verified by simulator ModelSim and then its quality was evaluated. To evaluate the core, We use Vnavigator for lint test and ModelSim for coverage check. During lint process, We adapted the OpenMORE's rule based on RMM (Reuse Methodology Manual) and it could tell us our IP's quality in a manner of the scored value form. If it is high, its quality is also high, and vice versa. During coverage check ModelSim-SE is used for verifying how our test circuits cover designs. This objective methods using well-defined commercial coverage metrics could perform a quantitative analysis of simulation completeness. In this manner, We evaluated the designed motor control IP's quality from the viewpoint of reuse. This methodology will save the time and cost in designing SoC that should integrate various IPs. In addition to this, It can be the guide for comparing the equally specified IP's quality. After all, we are continuously looking forward to enhancing our motor control IP in the aspect of not only functional perfection but also IP reuse to prepare for the SoC-Compliant motor control IP design.

In ebXML, a representative framework for electronic commerce, a BPS (Business Process Specification) should be finally defined as an instance of XML-version BPSS for the configuration of B2B (Business to Business) runtime systems . In order to define the instance more complete and consistent, it is required to validate all the semantic constraints on the instance . Due to the limitations of XML Schema constructs, however, current XML-version BPSS fails to specify formal semantic constraints completely. This paper presents how to find, express and reuse BPSS semantic constraints that could not be explicitly defined in the XML-version BPSS. The method facilitates the validation of XML-version BPSS instances easily with some useful guides for fixing violations of semantic constraints. Furthermore, B2B business processes can be standardized and applied more efficiently and effectively.

Component-based Software development(CBSD) is widely used in various area due to its efficiency of time, cost and effort. In the embedded software which has high dependency of platform and can be developed by product family, the efficiency of CBSD is maximized by reuse. These embedded software has various limitations of the resources. Specially, the effective energy consumption is very important in the portable embedded software such as smart phone and tablet PC, because they are operated with limited energy source like a battery. Therefore, energy efficient problem became very important issue in the CBSD. In this paper, we identified characteristics and environment that influence energy consumption of components. Afterward, we defined a component specification language which is consisted to describe energy characteristics of the components. This supposed specification language can be utilized to energy efficient component search and selection.

In this paper we propose an engineering bill of materials (E-BOM) copy method that can be utilized to manage the product information for each equipment during building a product lifecycle management (PLM) system in the order-specific semiconductor equipment manufacturer. The previous works studied on an E-BOM creation and management method for the mass manufacturing and production. The method is difficult to apply to an environment in which many engineering changes occur and the different specification to each equipment is required such as semiconductor equipments and facilities adopting built-to-order instead of built for inventory. Moreover the method is known to be the major drawback to deteriorate the design efficiency. Our E-BOM copy method enables users efficiently to manage the specification of a product and shortens the product development cycle. To implement the E-BOM copy method in the PLM environment, we developed the E-BOM copy system that automatically generates new parts and their numbers according to the numbering rule while copying the E-BOM from existing semiconductor equipments and then can apply the parts for reuse to new semiconductor equipments. This system can duplicate not only 3D CAD data but also technical documents.

Product line engineering(PLE) is one of the recent and effective reuse approaches that enables developing a number of applications by instantiating a core asset. Elements of a core asset are product line architecture(PLA), component, and decision model. Among these elements, PLA is the key element since it defines the overall structure of the core asset. Although numerous PLE methodologies have been introduced, it is still unclear what should be the elements of a PLA and how to systematically instantiate it for specific applications. Formal specifications can play a key role in defining detailed and precise instantiation process. In this paper, we first present a meta model of PLA and show how to specify PLA in a formal language, Object-Z. Then, we propose instantiation rules using formal specification and those rules precisely define constraints for instantiating PLA. By applying the proposed formal specification, we believe PLA instantiation can be carried out precisely and correctly, yielding high quality software development.

Avionics System Integration Laboratory is the integrated test environment for integration and verification of avionics systems. When real equipment can not be used in the laboratory for various reasons, software models should be needed. Because there hasn't been any standardized method for the models so that it is difficult to reuse the developed models, the need for a framework to develop the avionics software models was emerged. We adopted DEVS(discrete event system specification) formalism as the standardized modeling method for the avionics software models. Due to DEVS formalism is based on event-driven algorithm, it doesn't accord a legacy system which has sequential and periodic algorithms. In this paper, we propose real-time event-driven modeling and simulation method for SIL to overcome these restrictions and to maximize reusability of avionics models through the analysis of the characteristics and the limitations of avionics models.

Weapon systems for future war require operating various war scenarios that are getting complex. Similarly, modeling and simulation technique is getting attention to acquire more effective weapon systems. Several S/W tools exist for simulating small scale engagements which depict a kind of war. However, it is very hard to model combat objects more systematic, and reuse them. To overcome these difficulties, this paper presents a modeling methodology for simulating small scale engagement using the DEVS-formalism. In this paper, we systematically classified and defined combat objects, likewise, explain a framework for a small scale combat simulation.
