Designing in virtual reality: a comparison of problem-solving styles between desktop and VR environments

Abstract: With recent breakthroughs in VR devices, new potential of CAD as a design tool is anticipated. Based on the influence of design tools in ideation, we compared the problem-solving styles of WIMP (Wi...

Timing verification of an integrated circuit

Abstract: This disclosure describes a design tool that verifies timing of an integrated circuit design by partitioning the integrated circuit design's gate-level netlist into target cell partition netlists and performs transistor-level circuit simulation on each target cell partition netlist. The design tool performs a back tracing procedure on each target sequential cell to define the target cell partition netlists. The design tool then identifies timing modes that enable valid logical paths through the target cell partition netlists from source sequential cells to the target sequential cells. In turn, the design tool performs transistor-level circuit simulation (e.g., SPICE simulations) on each target cell partition netlist to check for timing violations based upon the timing modes. In one embodiment, the design tool includes clock tree delay information, power supply variations, or routing parasitic information in the simulations to achieve improved timing analysis accuracy compared with traditional static timing analysis or timing optimization.

Development of a Façade Assessment and Design Tool for Solar Energy (FASSADES)

Abstract: Planning energy-efficient buildings which produce on-site renewable energy in an urban context is a challenge for all involved actors in the planning process The primary objective of this study was to develop a facade assessment and design tool for solar energy (FASSADES) providing the necessary information for all stakeholders in the design process The secondary objective was to demonstrate the tool by performing an assessment analysis of a building block The FASSADES tool is a DIVA4Rhino script, combining Radiance/Daysim and EnergyPlus for simulating the annual production of solar thermal and photovoltaic systems on facades, the cost-effectiveness of the solar energy system, and the payback time Different output methods are available; graphically within the 3D drawing environment and numerically within post-processing software The tool was tested to analyse a building block within a city under Swedish conditions Output of the developed tool showed that shading from nearby buildings greatly affects the feasibility of photovoltaic and solar thermal systems on facades

Development of Detached Breakwater Design Criteria Using a Shoreline Response Model

Abstract: An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance, wave breaker height, wave period, depth at structure, and structure transmission were varied to develop a series of design nomographs for predicting morphological response. This type of design tool is intended for determining preliminary, feasibility-level project specifications. More detailed evaluations of candidate designs using a prototype test, and/or numerical/physical models with site-specific parameters are required to determine final project specifications. This paper discusses the study methodology and presents preliminary breakwater design nomographs.

Quantification of scene appearance—A valid design tool?

Abstract: Awareness of the science of appearance could help the designer to create and construct a more effective space—whether that consists of interiors, packaging, cityscapes or a plate of food. This article examines the current status of appearance science having direct application to the work of the practical designer using a vocabulary common to both disciplines. The way has been paved by the work of Shigenobu Kobayashi, of the Nippon Color and Design Research Institute, Paul Green-Armytage, a design teacher, and studies on food products and food consumption environments as well as on colour semantics studies of psychologists such as, for example, Lars Sivik and Charles Taft. The article is in two parts, appearance properties and expectations of the design and impact of the design. First, there is a brief account of the application of bipolar scales to quantify both the physical properties of the scene as well as our expectations of the scene and second, the quantification and understanding of scene impact. These techniques detail how individual elements of a designed space, such as materials, design and illumination contribute to specific desired aspects of the space. The robust model proposed provides a firm platform for active collaboration between designer and scientist in the production of comfortable and effective living and working spaces. © 2011 Wiley Periodicals, Inc.
