Available in PDF, EPUB and Kindle. Book excerpt: The demand is exploding for complete, integrated systems that sense, process, manipulate, and control complex entities such as sound, images, text, motion, and environmental conditions. These systems, from hand-held devices to automotive sub-systems to aerospace vehicles, employ electronics to manage and adapt to a world that is, predominantly, neither digital nor electronic. To respond to this design challenge, the industry has developed and standardized VHDL-AMS, a unified design language for modeling digital, analog, mixed-signal, and mixed-technology systems. VHDL-AMS extends VHDL to bring the successful HDL modeling methodology of digital electronic systems design to these new design disciplines.Gregory Peterson and Darrell Teegarden join best-selling author Peter Ashenden in teaching designers how to use VHDL-AMS to model these complex systems. This comprehensive tutorial and reference provides detailed descriptions of both the syntax and semantics of the language and of successful modeling techniques. It assumes no previous knowledge of VHDL, but instead teaches VHDL and VHDL-AMS in an integrated fashion, just as it would be used by designers of these complex, integrated systems. - Explores the design of an electric-powered, unmanned aerial vehicle system (UAV) in five separate case studies to illustrate mixed-signal, mixed-technology, power systems, communication systems, and full system modeling.
Download or read book Conceptual Level Analog Circuit Modeling in VHDL AMS as a Surrogate for Component Level Modeling written by and published by . This book was released on 2008 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardware Description Languages (HDLs) are used to model a circuit before the circuit is designed and built. VHDL-AMS is one such language which allows modeling of circuits and systems in both the analog and digital modes or both. VHDL-AMS allows the description of any circuit or a system at various levels of abstraction such as the behavioral level or the component level. The behavioral level is a higher level of abstraction whereas the component level is a lower level of abstraction. The level of abstraction is chosen such that a desired accuracy is obtained in minimum time. This thesis aims at developing behavioral models that accurately represent the function and performance of the system modeled at the component level in the analog domain. The surrogate used to develop this aim is the Amplitude Modulation Superheterodyne receiver. The design tradeoff that is mainly considered is the tradeoff between the accuracy and the simulation time. This trade off is discussed by studying the effects of the abstraction models on the system performance. In fact, knowing the contributions to system performance accuracy by each subcircuit model, the designer could "dial in" the circuit models with the fastest execution time consistent with the system performance accuracy desired.

Book excerpt: Discover how Verilog-A is particularly designed to describe behavior and connectivity of circuits and system components for analog SPICE-class simulators, or for continuous time (SPICE-based) kernels in Verilog-AMS simulators. With continuous updates since it's release 30 years ago, this practical guide provides a comprehensive foundation and understanding to the modeling language in its most recent standard formulation. With the introduction of language extensions to support compact device modeling, the Verilog-A has become today de facto standard language in the electronics industry for coding compact models of active and passive semiconductor devices. You'll gain an in depth look at how analog circuit simulators work, solving system equations, modeling of components from other physical domains, and modeling the same physical circuits and systems at various levels of detail and at different levels of abstraction. All industry standard compact models released by Si2 Compact Model Coalition (CMC) as well as compact models of emerging nano-electronics devices released by New Era Electronic Devices and Systems (NEEDS) initiative are coded in Verilog-A. This book prepares you for the current trends in the neuromorphic computing, hardware customization for artificial intelligence applications as well as circuit design for internet of things (IOT) will only increase the need for analog simulation modeling and make Verilog-A even more important as a multi-domain component-oriented modeling language. Let A Practical Guide to Verilog-A be the initial step in learning the extended mixed-signal Verilog-AMS hardware description language. You will: Review the hardware description and modeling language Verilog-A in its most recent standard formulation. Code new compact models of active and passive semiconductor devices as well as new models for emerging circuit components from different physical disciplines. Extend the application of SPICE-like circuit simulators to non-electronics field (neuromorphic, thermal, mechanical, etc systems). Apply the initial steps towards the extended mixed-signal Verilog-AMS hardware description language.

This book was released on 2012-12-06 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardware description languages (HDL) such as VHDL and Verilog have found their way into almost every aspect of the design of digital hardware systems. Since their inception they gradually proved to be an essential part of modern design methodologies and design automation tools, ever exceeding their original goals of being description and simulation languages. Their use for automatic synthesis, formal proof, and testing are good examples. So far, HDLs have been mainly dealing with digital systems. However, integrated systems designed today require more and more analog parts such as A/D and D/A converters, phase locked loops, current mirrors, etc. The verification of the complete system therefore asks for the use of a single language. Using VHDL or Verilog to handle analog descriptions is possible, as it is shown in this book, but the real power is coming from true mixed-signal HDLs that integrate discrete and continuous semantics into a unified framework. Analog HDLs (AHDL) are considered here a subset of mixed-signal HDLs as they intend to provide the same level of features as HDLs do but with a scope limited to analog systems, possibly with limited support of discrete semantics. Analog and Mixed-Signal Hardware Description Languages covers several aspects related to analog and mixed-signal hardware description languages including: The use of a digital HDL for the description and the simulation of analog systems The emergence of extensions of existing standard HDLs that provide true analog and mixed-signal HDLs. The use of analog and mixed-signal HDLs for the development of behavioral models of analog (electronic) building blocks (operational amplifier, PLL) and for the design of microsystems that do not only involve electronic parts. The use of a front-end tool that eases the description task with the help of a graphical paradigm, yet generating AHDL descriptions automatically. Analog and Mixed-Signal Hardware Description Languages is the first book to show how to use these new hardware description languages in the design of electronic components and systems. It is necessary reading for researchers and designers working in electronic design.

Available in PDF, EPUB and Kindle. Book excerpt: The Verilog Hardware Description Language (Verilog-HDL) has long been the most popular language for describing complex digital hardware. It started life as a prop- etary language but was donated by Cadence Design Systems to the design community to serve as the basis of an open standard. That standard was formalized in 1995 by the IEEE in standard 1364-1995. About that same time a group named Analog Verilog International formed with the intent of proposing extensions to Verilog to support analog and mixed-signal simulation. The first fruits of the labor of that group became available in 1996 when the language definition of Verilog-A was released. Verilog-A was not intended to work directly with Verilog-HDL. Rather it was a language with Similar syntax and related semantics that was intended to model analog systems and be compatible with SPICE-class circuit simulation engines. The first implementation of Verilog-A soon followed: a version from Cadence that ran on their Spectre circuit simulator. As more implementations of Verilog-A became available, the group defining the a- log and mixed-signal extensions to Verilog continued their work, releasing the defi- tion of Verilog-AMS in 2000. Verilog-AMS combines both Verilog-HDL and Verilog-A, and adds additional mixed-signal constructs, providing a hardware description language suitable for analog, digital, and mixed-signal systems. Again, Cadence was first to release an implementation of this new language, in a product named AMS Designer that combines their Verilog and Spectre simulation engines.

Download or read book A Methodology for Analyzing VDDL AMS Systems Using an Experimental Design Approach written by Vikram Krishnamachary and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Circuit simulation provide users with practical feedback when designing real world systems. This allows the designer to determine the correctness and efficiency of a design before the system is actually constructed. Consequently, the user may explore the merits of alternative designs without actually physically building the systems. Moreover with the time-to-market cost being the driving force in todays semiconductor industry, identifying faults early in the design process is critical. VHDL-AMS extends the modeling capabilities of VHDL to enable descriptions of high-level systems with continuous dynamic behavior that can be specified by means of algebraic or ordinary differential equations. Thus, a modeler in VHDL-AMS has the option of describing systems in almost any domain, whose properties can be represented by a set of ordinary differential equations. In any such model, there is going to be one or more responses of interest which the modeler would want to control. Hence there arises a need to provide an efficient methodology to the modeler which would enable him to determine the values of some circuit parameters in order to satisfy certain output specifications. Surprisingly, there has not been much development in this domain of VHDL-AMS modeling. A Design of Experiments approach provides an ideal backplane for this type of analysis where the goal is to obtain the maximum information with the minimum number of simulations. This thesis proposes a methodology using such an experimental design approach applicable to VHDL-AMS systems, where the aim is to efficiently determine the relative significance of the factors in a model on the output response of interest with the least number of simulations, for improving the performance of such systems.

Book excerpt: Today there is a continuing need for accurate and high-speed device models for pre-simulation of large circuits before fabrication. Further, with shrinking of transistor sizes, both analog and digital circuits are sharing the same chip space in today's integrated circuit design. As a result, mixed-signal simulators are becoming popular today. VHDL-AMS is a mixed-signal hardware design language which has the capability of modeling both digital and analog circuits at different level of abstraction. Unfortunately there are few transistor models directly implemented in VHDL-AMS. The models that do exist have largely been the result of research at Universities rather than industry-supported models. Further the transistor models that exist are oriented towards the microelectronic technology domain above 100nm. So far there exist no BSIM transistor models in VHDL-AMS capable of accurately modeling transistors in the sub-100 nm range. A candidate for a good deep submicron transistor model is the BSIM4 model. In this thesis we have used BSIM4.1 model to create a deep submicron transistor model for VHDL-AMS. It has been evaluated using realistic analog and digital test circuits for accuracy, robustness and performance. Equivalent test circuits were created in HSPICE to compare the results obtained from the VHDL-AMS model. The test results show that the BSIM4.1 VHDLAMS model performed well for all test circuits with maximum error less than 7% and an average error less than 2%.
