System design oriented RF block modeling : When top-down reaches bottom-up

open access: closed2007 IEEE International Behavioral Modeling and Simulation Workshop, 2007
This paper deals with a new RF block model implementation dedicated to the design of complex systems on chip. The hierarchical library have been developed with simulators that can be used in a single design platform, which ensure a unique simulation environment and a full interoperability between the models. This is the first step in the development of

Top-down vs bottom-up methodologies in multi-agent system design

open access: closedAutonomous Robots, 2008
Traditionally, two alternative design approaches have been available to engineers: top-down and bottom-up. In the top-down approach, the design process starts with specifying the global system state and assuming that each component has global knowledge of the system, as in a centralized approach.

Cross-layer optimization for wireless networks: top-down or bottom-up design?

open access: closed2009 International Conference on Communications, Circuits and Systems, 2009
In this talk, we discuss the cross-layer optimization issues in wireless networks by investigating the impact of physical (PHY) layers on the media access control (MAC) and higher protocol layers, or vice versa. In particular, we explore the benefits of cross-layer design for multi-user multi-input multi-output (MU-MIMO) cellular mobile networks ...

Top-Down Versus Bottom-Up Nanoengineering Routes to Design Advanced Oropharmacological Products

open access: closedCurrent Pharmaceutical Design, 2016
Energy intensive and chemical routes predominately govern modern dental material fabrication involving complex physicochemical approaches. Current interest in dental material design is shifting towards biomineralization method and green chemistry synthesis to support oral tissue biocompatibility and oropharmacology.

A fully qualified top-down and bottom-up mixed-signal design flow for non volatile memories technologies [PDF]

open access: closed2003 Design, Automation and Test in Europe Conference and Exhibition, 2005
The wide range and rapid increase in the complexity of EDA tools demand proven and safe design flows. This paper presents a complete and fully qualified mixed-signal top-down design flow for non volatile memory applications. It has been successfully applied to an embedded flash macrocell based design as well as to a 14 bit analog/digital converter with

Top-Down Bottom-Up Design Methodology for Fast and Reliable Serdes Developments in nm Technologies

open access: closed, 2008
This paper describes the development of high speed serial data communication links from the viewpoint of signal and circuit complexity. It proposes a development method to deal in qreliable and affordable with the increasing complexity. Two example implementations are discussed: a 10 Gbps link in 0.13 μm CMOS and a 2.5 Gbps PCI-Express link in 90 nm ...

Reconciling top-down and bottom-up design approaches in RMM

ACM SIGMIS Database: the DATABASE for Advances in Information Systems, 1998
The proliferation of intranets and extranets as well as the vast expansion of the World Wide Web (WWW) and electronic commerce indicate the need for a structured hypermedia design methodology that will guide the design, development, and maintenance of large multimedia and hypermedia information systems and collaborative systems.
