This document provides an outline for a lecture on hardware description language (HDL) programming. It discusses HDL overview and key concepts like Verilog and VHDL. Verilog was developed in the 1980s and became an IEEE standard in 1995. It uses modules as basic building blocks and has a C-like syntax. VHDL was developed for the Department of Defense and also became an IEEE standard. It uses a top-down design approach with entities, architectures, and configurations. Examples of coding in Verilog and uses of FPGAs are also provided.
VHDL is defined by IEEE. This standard is known by all the VHDL tool developers. So
there is only one language to learn. This language is used by all the circuit designers around the world. The life time for this language is assured, since it is an IEEE standards. Any investment or learning is assured for lifetime. Abundance of models available from different sources can be used with ease. Some tools might support Foreign Language Interface, by which you can add your model in C language to the VHDL code. It is a modern language, powerful and general. Other advantages include readability of the code and portability. The code developed is portable to any technology at any time. Time to market is short (leads to leadership in the market). Any error found during the simulation phase is less expensive than by discovering the errors after making the circuit board (Investment is saved). The great advantage is that the Project Managers can modify the specification without leading to disaster (only the necessary portion of the code need to be changed). It can deliver designs 100% error free at short duration. New Concepts in
hardware design (for example, in image processing, DSP, etc.,) can be modeled in VHDL and its efficiency or viability can be proven without doing the hardware. A large number of ASICs fail to work when plugged into a system even if they meet their specifications first time. VHDL addresses this issue in two ways: A VHDL specification can be executed in order to achieve a high level of confidence in its correctness before commencing design, and may simulate one to two orders of magnitude faster than a gate level description. A VHDL specification for a part can form the basis for a simulation model to verify the operation of the part in the wider system context (e.g. printed circuit board simulation). This depends on how accurately the specification handles aspects such as timing and initialization.

Solution
VHDL (Very High Speed IC Hardware description Language) is one of the standard hardware description language used to design digital systems. VHDL can be used to design the lowest level (gate level) of a digital system to the highest level (VLSI module). VHDL though being a rigid language with a standard set of rules allows the designer to use different methods of design giving different perspectives to the digital system. Other than VHDL there are many hardware description languages available in the market for the digital designers such as Verilog, ABEL, PALASM, CUPL, and etc but VHDL and Verilog are the most widely used HDLs. The major difference between hardware description programming languages and others is the integration of time. Timing specifications are used to incorporate propagation delays present in the system

A hardware description language enables a precise, formal description of an electronic circuit that allows for the automated analysis and simulation of an electronic circuit. It also allows for the synthesis of an HDL description into a netlist (a specification of physical electronic components and how they are connected together), which can then be placed and routed to produce the set of masks used to create an integrated circuit.

JDD2015: Towards the Fastest (J)VM on the Planet! - Jaroslav TulachPROIDEA
TOWARDS THE FASTEST (J)VM ON THE PLANET!
When designing new language, one usually starts with an AST interpreter. When the language is ready for use, users find out it is great, but slow. So one starts to design a bytecode to speed things up. That may help a bit, but usually the result is clear: still the execution is slow. Truffle project offers you a different perspective: write your AST interpreter using Truffle nodes API and we make it fast! In addition to that we also give you tooling for free! As a proof we'll demonstrate that our implementation of Ruby is ten times faster than any other one, including indy based JRuby. Stop by for a short introduction how to be create the fastest execution environment for any language!
This Presentation covers most of VHDL designing basic from scratch.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Outline
3. ¿VHDL & Verilog?
Hardware description language (HDL) is a specialized computer
language used to describe the structure and behavior of electronic
circuits, and most commonly, digital logic circuits.
There are two most common Hardware Description Languages (HDL)
used by integrated circuit (IC) designers.
Verilog HDL
VHDL.
They are each a notation to describe the behavioral and structural
aspects of an electronic digital circuit.

4. VHDL Background
VHSIC Hardware Description Language.
VHSIC is an abbreviation for Very High Speed Integrated Circuit.
Developed by the department of defense (1981)
In 1986 rights where given to IEEE
• Became a standard and published in 1987
• Revised standard we know now published in 1993 (VHDL 1076-1993)
regulated by VHDL international (VI)
4
12/6/2020 Dr Salah Alkurwy
5. VHDL
Uses top-down approach to partition design into small blocks
‘components’
Entity: describes interface signals & basic building blocks
Architecture: describes behavior, each entity can have
multiple Architectures
Configuration: sort of parts list for a design, which behavior
to use for each entity.
Package: toolbox used to build design

7. • VHDL represents another high level language for digital
system design.
• In this course we study Verilog HDL
– reason:
• used more often in electronic and computer industry
• programming style is very similar to C programming
language

8. Verilog Background
Developed by Gateway Design Automation (1980)
Later acquired by Cadence Design(1989) who made
it public in 1990
Became a standardized in 1995 by IEEE (Std 1364)
regulated by Open Verilog International (OVI)
8
Gateway Design Automation. The company was privately held at that time by Dr. Prabhu
Goel, the inventor of the PO in 1985 DEM (Path-Oriented Decision Making) test generation
algorithm.[1] Verilog HDL was designed by Phil Moorby who was later to become the Chief
Designer for Verilog-XL
12/6/2020 Dr Salah Alkurwy
9. • Verilog only has one building block
– Module: modules connect through their port similarly as
in VHDL
– Usually there is only one module per file.
– A top level invokes instances of other modules.
– Modules can be specified behaviorally or structurally.
• Behavioral specification defines behavior of digital system
• Structural specification defines hierarchical interconnection of
sub modules

An Example of Verilog HDL Cde
11. • Verilog Hardware Description Language(HDL)
– A high-level computer language can model, represent and simulate digital
design
• Hardware concurrency
• Parallel Activity Flow
• Semantics for Signal Value and Time
– Design examples using Verilog HDL
• Intel Pentium, AMD K5, K6, Atheon, ARM7, etc
• Thousands of ASIC designs using Verilog HDL
What is Verilog HDL?
11
12. The “standard” languages are:
Very similar
Many tools provide front-ends to both
Verilog is “simpler”
Less syntax, fewer constructs
VHDL supports large, complex systems
Better support for modularization
More grungy details
“Hello world” is much bigger in VHDL
Verilog/VHDL
12
13. • These languages have taken designers from low level detail to
much higher level of abstraction.
• In 2000 VI & OVI merged into Accellera
• Simulation & synthesis are the two main kinds of tools which
operate on the VHDL & Verilog languages.
• They are not a toolset or methodology they are each a different
language.
– However toolsets and methodologies are essential for their effective use.
Similarities
13
12/6/2020 Dr Salah Alkurwy
14. • There are not many differences as to the capabilities of
each.
• The choice of which one to use is often based in personal
preference & other issues such as availability of tools &
commercial terms.
• VHDL is “harder” to learn ADA-like.
• Verilog is “easier” to learn C-like.
Differences?

15. Field Programmable Gate Array
A Fully configurable IC
FPGAs contain programmable logic components called logic blocks.
Contain hierarchy of reconfigurable interconnects that allow the blocks to be
wired together.
Logic Blocks can be configured to any complex circuit.
FPGA can be made to work as a Xor gate, a Counter or even bigger- an
entire Processor!
