Reflection and automated introspection of a design in system level design frameworks are seen as necessities for the CAD tools to manipulate the designs within the tools. These features are also useful for debuggers, class and object browsers, design analyzers, composition validation, type checking, compatibility checking, etc. However, the central question(More)
We consider the type inference problems in a compositional design environment where the components are automatically instantiated from pre-existing C++-based intellectual property (IP) libraries. We present a component integration language based on scripting for design specification. Our focus is architectural aspects in specification that uses aggregation-(More)
This article describes the Balboa component integrationenvironment that is composed of three parts: a script languageinterpreter, compiled C++ components, and a set ofSplit-Level Interfaces to link the interpreted domain to thecompiled domain. The environment applies the notion ofsplit-level programming to relieve system engineers of softwareengineering(More)
Morin-aluminium fluorescence and membrane filtration were successfully applied to the indirect identification of the formation of hydroxyaluminosilicates (HAS) in acidic solutions of varying pH and of known concentrations of aluminium (Al) and silicic acid (Si(OH)(4)). It was proven to be especially useful in providing evidence of the strong competition(More)
Rising complexity and performances, shortening time-to-market demands, stress high-level embedded system design as a prominent research topic. Ad-hoc design methodologies, that lifts modeling to higher levels of abstraction, the concept of intellectual property, that promotes reuse of existing components, are essential steps to manage design complexity,(More)
Design visualization is an important part of the system design process. In practice, systems are often visualized using a combination of structural and functional entities. In this paper, we describe an approach that helps to capture the structural aspects of a design at a high level of abstraction and enables the system designer to enter designs(More)
—This paper presents the BALBOA component composition framework for system-level architectural design. It has three parts: a loosely-typed component integration language (CIL); a set of C++ intellectual property (IP) component libraries; and a set of split-level interfaces (SLIs) to link the two. A CIL component interface can be mapped to many different C++(More)
System-on-chip design introduced many new challenges for engineers. Among them, complexity management and reuse are important issues. Many efforts address complexity by raising the level of abstraction to increasingly functional levels. However, at any level of abstraction, structural information is as important as functionality for microelectronic design.(More)
This research has evaluated the ability of cross-flow filtration (CFF) to perform correct size fractionation of natural aquatic colloids (materials from 1nm to 1mum in size) and particles (>1mum) using scanning electron microscopy (SEM) combined with atomic force microscopy (AFM). SEM provided very clear images at high lateral resolution (ca. 2-5nm),(More)
