A Methodology for Reusable Physical Design

Summary form only given. For many VLSI designs, validation has started to dominate the total design effort. In addition, historical trends are indicating that this problem will continue to grow. For example, data from Intel's lead microprocessor design efforts shows that the number of pre-silicon bugs has increased by a factor of four for every lead project for the last 25 years. If this trend is not broken, Intel's next lead design is likely to have to go through the find the bug, evaluate it, root cause it, it, and validate the fix process tens of thousands of times; potentially overwhelming the validation and design team. Thus one of the most critical goals for improving the design process is to break this bug trend. In the presentation, we introduce the integrated design and verification (IDV) system that has been developed at Intel for the last 5 years. IDV combines the design and validation efforts so that the task of design validation (i.e., Did we capture what we actually wanted?) is significantly simplified by means of a much smaller and much more stable high-level model. Furthermore, when the design is completed, so also is the implementation validation (i.e., Did we implement what we intended?). The latter is accomplished by linking the design process very tightly with the validation process. Although this idea is not new, the combination of correct-by-construction and correct-by-verification and the tight integration of a database of verified results is new and has led to a design environment that allows rapid design in which the validation problem has been significantly reduced. To make the presentation more realistic, we will use the design, from a high-level model to layout, of a floating point execution unit as a driving example. We discuss the early design phase in which the high-level model is refined using algorithmic transformations to a viable micro architecture; continue with the middle level design in which the actual logic implementation is derived and conclude with the final placement and layout stage. Although the design process conceptually is performed sequentially, we will illustrate the tight loop that IDV enables between physical design and logical/micro-architectural design. The latter is a critical component in enabling design convergence. In fact, in today's process technology, integration of physical and logical design is not optional but rather mandatory.

The two stages of database design are logical and physical design. Logical database design, also referred to as , is done first. It is the process of studying the workings of a business organization, constructing a set of tables to store the business data, and understanding the constraints on the data, the dependencies between the tables, and the business rules concerning the data. The logical database design process is conducted without reference to any specific database technology such as Oracle or Microsoft SQL Server. Tools such as SQL Developer Data Modeler and Toad Data Modeler can be used for the purpose. Physical database design follows logical database design. First, the logical model is mapped to the proprietary features of the chosen database technology. Security requirements, integrity requirements, and business rules are also implemented. Finally, you consider performance: the ability of the database engine to handle work requests efficiently. This typically involves the creation of indexes on the data, and Oracle Database provides a wealth of indexing mechanisms to choose from.

Computer Science is being increasingly used in medicine to improve quality of care and patient outcome. Clinical Decision Support Systems (CDSSs) that codify clinical Best Practice Guidelines (BPGs) and provide situation-specific advice to physicians CDSSs have shown effectiveness in reducing adverse patient outcomes during clinical evaluations. However, representing both the BPG and the associated physical processes in software is complex and tedious, making CDSSs prone to bugs. This can be mitigated using a modular software architecture that encapsulates computational representation of physical processes for finer-grained development and verification leading to improved comprehensibility, shareability and maintainability. This paper discusses the sources of complexity in CDSSs, and proposes a software architecture that consists of an encoding of the BPG's medical knowledge into executable representations comprising of a patient digital twin, diagnosis and treatment workflows, an adherence monitor, a User Interface (UI) and a middleware for seamless integration with existing Hospital Information Systems. We developed a CDSS for Pediatric Sepsis Management co-designed by physicians using our approach. We use the Fluid Resuscitation therapy of this CDSS as a case study to illustrate the development process.

The level of complexity and the turn-around time associated with the development of custom bipolar VLSI chips have defined the need for a highly structured physical and electrical design validation approach which can guarantee fully functional first-pass chips, yet be flexible enough to allow logical and physical designers the latitude necessary to achieve specified cost and performance objectives. This paper describes such a design verification strategy and its implied constraints on chip design. The rationale for comparing the logic equivalence of the high-level logical models to the low-level-device physical models is presented, a description of the hierarchical logical-to-physical and electrical checking is given, and its impact on cost and complexity is examined.

One of the most fundamental and most highly debated questions in Information Systems education is the role of programming in undergraduate IS programs. On one hand, there are strong arguments and precedents supporting not only the inclusion of programming in these programs but also a significant role for it. For example, both the most recent model curriculum (IS 2002) and many existing undergraduate IS programs include a significant programming component. IS 2002 incorporates a programming course with a highly complex name reflecting the ambiguity about the focus of the course ("Programming, Data, File, and Object Structures,") but it also includes two additional courses that have significant programming components ("Physical Design and Implementation with DBMS" and "Physical Design and Implementation in Emerging Environments"). The "Analysis and Logical Design" course is directly connected to application development/programming. A closer evaluation of the course descriptions reveals a very ambitious agenda; the topics include items such as "programming in traditional and visual environments that incorporate event-driven, object-oriented design," "algorithm development," "program correctness, verification, and validation," "structured and object design approaches," and "structured, event driven, and object oriented application design." This choice of wording, which is practically unchanged from IS'97, signifies a strong commitment to developing the students' programming and software development capabilities. In addition, the general criteria for accrediting undergraduate computing programs (including those in information systems) clearly include programming activities (3 (c)) "The program enables students to achieve, by the time of graduation, ... an ability to design, implement, and evaluate a computer-based system, process, component, or program to meet desired needs.

A data warehouse is a repository of data that can be analyzed to gain a better knowledge about the “goings on” in a company. The value of better knowledge can lead to superior decision making. Although this architecture has been around for a long time its use is not wide spread. Many researchers have noted the absence of its penetration in business. So, while on the one hand we find a rapid growth in the e-commerce industry and advances in hardware and software, on the other hand, very few companies seem to know how to use data warehousing technologies to succeed in e-commerce. There are companies that have successfully incorporated a data warehouse and have become pioneers and leaders in e-commerce. This article presents the success of Amazon. com in the business to consumer sector of e-commerce and the success of Wal-Mart as the leader in the business to business sector of e-commerce. Data warehousing and electronic-commerce are two of the most rapidly expanding  elds in recent information technologies. In this paper, we discuss the design of data warehouses for e- commerce environment. We discuss requirement analysis, logical design, and physical design issues in e-commerce environments. We have collected an extensive set of interesting OLAP queries for e-commerce environments, and classi ed them into categories. Based on these OLAP queries, we illustrate our design with data warehouse bus architecture, dimension table structures, a base star schema, and an aggregation star schema. We  nally present various physical design considerations for implementing the dimensional models. We believe that our collection of OLAP queries and dimensional models would be very useful in developing any real-world data warehouses in e-commerce environments.

This paper discusses the design, development and deployment of a large projected multi-touch surface within a rural context. Based on our previous work we deployed the system and worked in a real world setting in order to understand how it might be used in this particular scenario and to further understand the issues involved in using such systems in a rural context. Such systems are often deployed in urban or lab-based scenarios, however rural settings come with their own set of issues that can often make them very different in terms of design implications from urban settings, and it is important to understand how these issues can impact upon both the design of the interface and the whole system. This innovative research engaged with the local community and this enabled us to further understand how we might advance the use of the system, in terms of its interface, software architecture and physical design. This paper discusses the impetus for the design of the system, the methods we used to frame our studies, the technical development and design of the system, and some findings from the actual deployment.

The importance of physical and nonphysical architectural design values made architectural designers need good experience to be experts of architectural values reasonably without neglecting any value in the design process. The importance of such values made that ignoring any values and mistakes occurs in the design process. Simultaneously, architectural designers' different nature and the difference in their experiences are causing different understandings of the design values, thus causing architectural mistakes. The research problem appears from the randomly propagating of mistakes in contemporary architecture, which is about to become a phenomenon in Al Sulaymaniyah city. The research aims to find the main reasons and influences of making architectural mistakes and propagating such mistakes in the contemporary architectural design depending on randomly selected samples. The study took the factor of "Architectural Designers' Experience" as an influential factor in avoiding the propagation of architectural mistakes. To see architectural mistakes in real existing cases, the research took some of the different types of residential buildings in Al Sulaymaniyah city designed during (2000-2010) as case study to show architects' architectural mistakes in residential buildings
