Novel Synthesis Methodology in Digital IC Design and Automation to Reduce NRE costs and Time-to-Market

The number of incremental and iterative steps in the digital IC design & automation methodology will decide the non-recurring-engineering (NRE) costs and time-to-market (TTM). Since the aforementioned factors are the major driving factors of the IC design industry, many algorithms were proposed in the last few decades to minimize/optimize the number of design steps in the conventional digital IC design & automation methodology. However, the conventional front end and back end designs have been carried out separately, which has limited the further minimization of design steps. Here we propose a novel digital IC design & automation methodology, which reduces the NRE costs and TTM by merging the front end and back end designs partially. It maps the input RTL description directly to their corresponding physical layouts(derived using the existing CAD tools and stored in a pre-computed library) without going through the all the steps in conventional logic and physical synthesis process. As part of the proposed methodology, we use a pre-computed library which stores all required physical layouts and their Boolean functions. We have exploited the functional symmetry and negation-permutation-negation (NPN) class representations to decoct the library size and number of comparisons. The functional symmetry reduced the number of required pre-computed circuits in our experiments from ] 1031 to 222 (464.4% reduction in the memory size) and helps in maintaining the regularity in the design, which is a major concern for engineering change order

A New Dynamic Library Based IC Design Automation Methodology Using Functional Symmetry with NPN Class Representation Approach to Reduce NRE Costs and Time-to-Market

Todays Electronic Design Automation industry is greatly affected by increased Non Recurring Engineering (NRE) costs and Time-to-Market (TTM) due to the incremental and iterative steps followed in the conventional digital IC design and automation flow. Reducing NRE cost and TTM at the same time is a daunting task to the research community without compromising on the performance. However, the complexity of hierarchical design steps can be reduced drastically by mapping the input register-transfer level (RTL) description directly to their corresponding physical designs stored in pre-computed technology libraries. We use the Dynamic Libraries, which store the layouts of the already designed blocks and their references for the later use in further designs which reduces the design time and design cost significantly. Further we have exploited the functional symmetry and negation-permutation negation (NPN) class representations to decoct the library size and number of comparisons to further improvise on design time which results in reduced TTM. The functional symmetry reduced the number of required pre-computed circuits in our experiments from 1031 to 222 (464.4% reduction in the memory size). We further validated our methodology with adders and multiplier blocks which are the basic elements of any processor or controller

Digital System Design - Use of Microcontroller

Embedded systems are today, widely deployed in just about every piece of machinery from toasters to spacecraft. Embedded system designers face many challenges. They are asked to produce increasingly complex systems using the latest technologies, but these technologies are changing faster than ever. They are asked to produce better quality designs with a shorter time-to-market. They are asked to implement increasingly complex functionality but more importantly to satisfy numerous other constraints. To achieve the current goals of design, the designer must be aware with such design constraints and more importantly, the factors that have a direct effect on them.One of the challenges facing embedded system designers is the selection of the optimum processor for the application in hand; single-purpose, general-purpose or application specific. Microcontrollers are one member of the family of the application specific processors.The book concentrates on the use of microcontroller as the embedded system?s processor, and how to use it in many embedded system applications. The book covers both the hardware and software aspects needed to design using microcontroller.The book is ideal for undergraduate students and also the engineers that are working in the field of digital system design.Contents• Preface;• Process design metrics;• A systems approach to digital system design;• Introduction to microcontrollers and microprocessors;• Instructions and Instruction sets;• Machine language and assembly language;• System memory; Timers, counters and watchdog timer;• Interfacing to local devices / peripherals;• Analogue data and the analogue I/O subsystem;• Multiprocessor communications;• Serial Communications and Network-based interfaces
