Mentor Graphics
Objective
To complete all aspects of the exercise regarding D type flip-flop, TTL and CMOS and to familiarize us with the HDL software which is Mentor Graphics. This software is capable of constructing and simulating a particular design.
As for this assignment 1, we are given 4 weeks to complete the assignment. It is compulsory to attend every lab sessions as there is no alternative software to use. Only a certain limit of time is given for the use of the software and therefore designing of circuit is required to be completed before attending the lab. To give students a first-hand understanding of the EDA lab and most importantly Mentor Graphics, a powerful tool in HDL technology.
This assignment allows the students to understand or rather familiarize themselves with the design flow of the EDA software and to fully explore what the software is capable and powerful to do.
Lastly, to prepare the students for the next assignments which uses the similar software.
Introduction – D(elay) Flip-Flop (What You Have to Know First!) The D flip-flop is useful when a single data bit (1 or 0) is to be stored. An additional inverter to the S-R flip-flop at the R input creates a D flip-flop. The D flip-flop shown below is a modification of the clocked SR flip-flop. The D input goes directly into the S input and the complement of the D input goes to the R input. If there is a HIGH on the D input when a clock pulse is applied, the flip-flop SETs and stores a 1. If there is a LOW on the D input when a clock pulse is applied, the flip-flop RESETs and stores a 0. The truth table below summarizes the operations of the positive edge-triggered D flip-flop. As before, the negative edge-triggered flip-flop works the same except that the falling edge of the clock pulse is the triggering edge.

In order to ensure a successful ERD, several tasks will need to be executed. One of the constraints we are presented with is the potential lack of documentation. One way to overcome this constraint will be to interview subject matter experts and the key players involved in the maintenance process. The first requirement will be to draft an Entity-Relationship Diagram (ERD) based upon the business rules and the entities, which were captured by Smith Consulting. All of Huffman’s hubs will use the database and with that, will need to be robust enough to handle the volume.
The main idea is to choose a manageable area within the department of choice and refine the practices and procedures before going company or enterprise wide. The organization will also use this time to determine how best to configure the various EDMS products to meet unique requirements. Of most importance is to configure, not change the way in which people work. The EDMS product set should be both highly configurable and extendable and in most cases will contain a superset of the functionality the organization will require.

This report presents the implementation of a Clock element and the use of the seven segment display on the Altera DE2-115 board. This experimentation with the clock and display are valuable since they are a precursor to future labs to come. In order to make these items work it required the use or Verilog code, which was given for parts 1, 2, and 3.
Figure 2.4 shows A Digital clock signal used for synchronize different part of circuit. It has only two values, high and low. A word, “clock” used in this report means the...
According to a poll question that was conducted in 2012 by graphicdesign.com, about 93% of Graphic Designers agreed to the statement that the Graphic Design industry is in bad shape and do not know where the discipline is headed. The root of Graphic Design is communication of an idea through art or graphics. And it has been in human history for the longest time, from cave drawings to hieroglyphs and from physical prints to the digital media. It has become a well-established industry but many of those who have been working as graphic designers for years see that it is heading nowhere, and that it has sustainability issues. But because the industry is adaptable, has economic advantages and because there is a great need of appealing and enticing art that communicates, the Graphic Design industry will develop, prosper and stand out of other creative industries since adaptable, economically advantageous and essential industries that offers a service that no other will, will develop, succeed and stand out.
Previously we have discussed the detail study of the system that analysis the requirements . While the requirements specification activity is entirely in the problem domain, design is the first step in moving from the problem domain toward the solution domain. Design is essentially the bridge between requirements specification and the final solution for satisfying the requirements[]. In this chapter we will produce a model that represent the system which can be used later to build the system. In the next sections we are going to discuss the architectural design of Smart Course. The architecting process can be thought as a decision making process in which the appropriate decisions must be made. Upon to that we will answer and clarify fundamental questions like: is the system centralized or distributed, how the system will be decomposed into model, which control , organization and reference model are selected. Moreover, we describe the main model that represent the Smart Course.

The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
META Group. Inc has an enterprise architecture planning process that avails a systematic way to aligning information technology projects to IT organizations with corporate priorities and objectives. META Group is an international organization that deals with advisory and consulting issues internationally. It`s role is to provide advice on technology and business strategies. It has provided these services to more than three thousand, three hundred clients across the world in over forty countries. META Group has used an enterprise architecture tool known as Model Driven Architecture (MDA). This tool has the capacity of implementing enterprise systems that are made known by the enterprise architecture process. Therefore, it provides a broad loom to the development and management of IT environments (Buchanan, 2002).
