Software design consists of determining a high-level organization of a system that meets a given problem specification. We present a prototype system called KASE (Knowledge Assisted Software Engineering) that helps system analysts and designers design and redesign software systems. The KASE environment provides knowledge representation and reasoning tools to integrate knowledge about general so...

Metropolis is a system design environment in which designs are carried out by a well-de ned methodology that orthogonalizes and localizes design concerns, captures design decisions and requirements explicitly and unambiguously, and exploits the underlying theoretical framework to e ectively apply a tool-set throughout the design phases. The project, supported by the Gigascale Silicon Research C...

The geographical separation of the users and insufficient input from pairs may cause undesired costs in interior/exterior design process. If immersive communication and interaction exist between the pairs, those undesired costs will be minimal. Lack of communication and understanding causes much of the design works to be lost as it is improperly passed on and/or incompletely understood. The com...

The designer proceeds with his work by collecting and combining knowledge about the design object; in so doing, the knowledge possessed by the designer is organized and extended. In cooperative design performed by multiple persons, this organized knowledge is shared among them. This study proposes a designer support environment in which design knowledge is organized by using conceptual systems ...

An advanced integrated environment is being developed at JPL that links collaborators who wish to perform interactive design analyses and/or mission simulations. The environment utilizes commercial technology (such as 3D visualization) where applicable, but key pieces are currently provided by soflware developed in-house for mission and spacecraft modeling. It allows a mission scenario to be bu...

The release of a CMOS low power library by the Infopad group at UC Berkeley gave engineers the ability to develop low power circuits with standard cells in Magic with minimum geometry layouts [1]. We describe a process that translates this low power standard cell library from Magic into the Mentor Graphics (MGC) environment. Using the Design Kit Example (DKE), we describe the steps to build a c...

Over the last decade many research groups have been developing reengineering environments. However, many design decisions such as support for multiple models, incremental loading of information, tool integration, entity grouping, and their impacts on the underlying meta-model and resulting environment have remained implicit. Based on the experience accumulated while developing the Moose reengin...

Modern high-performance embedded systems, such as Automatic Target Recognition for Missiles or Dynamic Protocols Mobile Communications devices, face many challenges. Power and volume constraints limit hardware size. Accurate, high-performance algorithms involve massive computations. Systems must respond to demanding real-time specifications. In the past, custom application-specific architecture...

Xfuzzy is a CAD tool that eases the development of fuzzy systems from their conception to their final implementation. It is composed of a set of modules and programs that share a common specification language and cover the different stages of the design process. Modules for describing, verifying and tuning the behavior of the system are integrated within the environment. In addition to these fe...

Classically, the computer has been used in signal processing simply for numerical calculations, leaving the majority of the design process has been unsupported: in particular, the analysis of the properties of the selected algorithm and the rearrangement of the algorithm to find efficient, input/output equivalent implementations. This paper explores some of the issues involved in supporting the...
