That is to say, VHDL was developed as an alternative to huge, complex manuals which were subject to implementation-specific details. The idea of being able to simulate these "documents" was so obviously attractive that logic simulators were developed that could read the VHDL files. The next step was the development of logic synthesis tools that read the VHDL, and output a definition of the physical implementation of the circuit. Modern synthesis tools can extract RAM counter , and arithmetic blocks out of the code, and implement them according to what the user specifies. Thus, the same VHDL code could be synthesized differently for lowest cost, highest power efficiency, highest speed, or other requirements.

: What is GHDL , Previous: Introduction , Up: Introduction 1.2 What is VHDL VHDL is an acronym for Very High Speed Integrated Circuit Hardware Description Language which is a programming language used to describe a logic circuit by function, data flow behaviour, or structure. VHDL is a programming language: although VHDL was not designed for writing general purpose programs, you can write any algorithm with the VHDL language. If you are able to write programs, you will find in VHDL features similar to those found in procedural languages such as C Pascal or Ada VHDL derives most of its syntax and semantics from Ada . Knowing Ada is an advantage for learning VHDL (it is an advantage in general as well). However, VHDL was not designed as a general purpose language but as an HDL (hardware description language). As the name implies, VHDL aims at modeling or documenting electronics systems. Due to the nature of hardware components which are always running, VHDL is a highly concurrent language, built upon an event-based timing model. Like a program written in any other language, a

It gives a strong description of the basic language features, including the ones usually skipped in intro texts. It skips the baby steps of logic design, and shows examples of most language constructs, including overloading. I never thought I'd say it, but this VHDL book is actually a bit weak on the hardware side. It's description of processes and events seems incomplete, and the discussion of timing-related features is scant. The description of synthesis is too brief to cover many of the common variations you'll come across. If you have scars from a few optimizing compilers, though, you'll be able to pick up what you need from your tools, co-workers, and experience. Place-and-route is worth understanding. Taking real control of it, though, is usually something done cautiously and within the context of specific tools and chip characteristics. A few chapters of the book focus on specific tools - naturally, not the ones I use. I found those missable. On the whole, I find this book helpful. Perhaps other books are better, but lots of books are lots worse.

68. VHDL Introduction Execution of a vhdl program results in a simulation of the digital system. We can view vhdl as a programming language for describing the generation of http://www.csee.umbc.edu/~plusquel/vlsi/slides/vhdl.html

VHDL Introduction A language for describing the structural, physical and behavioral characteristics of digital systems. Execution of a VHDL program results in a simulation of the digital system. Allows us to validate the design prior to fabrication. The definition of the VHDL language provides a range of features that support simulation of digital systems. VHDL supports both structural and behavioral descriptions of a system at multiple levels of abstraction. Structure and behavior are complementary ways of describing systems. A description of the behavior of a system says nothing about the structure or the components that make up the system. There are many ways in which you can build a system to provide the same behavior. Reference: "VHDL Starter's Guide", Sudhakar Yalamanchili, Prentice Hall Events, Propagation Delay and Concurrency VHDL allows you to specify: The components of a circuit. Their interconnection. The behavior of the components in terms of their input and output signals. What are its behavioral properties of the half-adder circuit ?

Technology AuviTran is a technology company specialising in the development, design and manufacture of innovative audio and video networking services, solutions and products. AuviTran solutions and products are based on the following technologies : EtherSound : providing very low latency, multi channels audio networking. FPGA/VHDL : for flexibility and easy customisation of product IP streaming : allowing the distribution, management and control of audio and video streaming over IP. Linux system : enabling cost effective and efficient embedded solutions EtherSound TM provides a cost effective fully digital path between a virtually infinite number of networked audio devices with up to 64 channels of 24-bit digital audio at 48 KHz, plus bi-directional status and control data. Off-the-shelf Ethernet components such as 100baseTX switch can be used to extend the number of audio devices, as well as the distance between the devices on the network. FPGA/VHDL FPGA for "Field-Programmable Gate Array" is a type of logic chip that can be programmed. An FPGA is similar to a PLD, but whereas PLDs are generally limited to hundreds of gates, FPGAs support thousands to millons of gates. The FPGA-architecture consists of many logic-modules, which are placed in an array-structure. The channels between the logic-modules are used for routing. The array of logic-modules is surrounded by programmable I/O-modules and connected via programmable interconnects. This freedom of routing allows every logic-module to reach every other logic-module or I/O-module. The worldwide first PLD with FPGA-architecture was developed by Xilinx in 1984.

OPTIONS Description I would like a VHDL program for implementation in an FPGA of the Learnable Evolution Model. The VHDL-LEM has to have a configuration file for setting up problems to be solved, (neural network circuit modules) preferably using the TIMBRE compiler to take a text configuration file and translate it into VHDL for loading into the source tree for the VHDL-LEM and programming into an FPGA utilizing the XILINX suite of tools. The LEM has to have a simulator to test the offspring and feed it back into the LEM for further evolution if needed. The output of the final "offspring" should be automatically generated in VHDL (if feasible). For more information on LEM see http://www.mli.gmu.edu/mresearch.html and for the TIMBRE script translation engine http://www.compusmart.ab.ca/rc/Timbre/timbre.htm

The RASSP Digest - Vol. 4, June 1997 VHDL International's University Program by Mahendra Jain, Executive Director, VHDL International VHDL International is a nonprofit organization whose mission is to cooperatively and proactively promote VHDL as a standard worldwide language for the design and description of electronic systems. With VHDL International's commitment to supporting electronic systems designers, semiconductor suppliers, EDA companies and others in the industry, VI sought to assess whether the upcoming generation of electrical engineers have tools and the training they will need to take part in the post-digital electronics industry. In 1994, VHDL International completed a major education survey. The objective was to assess the level of VHDL knowledge of BSEE graduates and what steps VI can take to increase the VHDL knowledge in engineering schools. This survey was completed by Texas Instruments in the US. Toshiba in cooperation with Electronic Industries Association of Japan completed a similar survey in Japan. VI found undergraduate BSEE students receive significant training in UNIX/C programming environment, but little training in specific HDLs, such as VHDL or other HDLs. Based on the results of the survey it was determined that only 14% of the US graduating seniors and 2% of the Japanese graduating seniors had a working knowledge of VHDL.
