CAD Frameworks And EDA Standardization

September 26th, 2014

cdafFrameworks, are only important to end users after they’re integrated with the users’ EDA tools. Deme Clainos, director of marketing for frameworks at Mentor Graphics, Wilsonville, Ore., lists the benefits of an integrated framework as follows: users can use any design tool from any vendor in the same consistent way with the same data (not have to reenter it for every new tool); users can keep track of the most recent (or any set of) versions of a design; and users can work on a specific portion of the design, regardless of what the other project members are doing, and have their portion automatically linked up with the overall project. Clainos adds that if the vendor and/ or system integrator is …

Britain’s Solution To The Snoring Problem

September 23rd, 2014

Snoring is quite a problem in England with about 40% of people there snoring. This statistic was reported by British Snoring and Sleep Apnea Association. The incidence is more common in people from the ages of 40 to 60 and in men more than in women. It is perhaps because of this situation that the organization British Snoring and Sleep Apnea Association was created.

As obesity becomes more commonplace, snoring problems are increasing.

As obesity becomes more commonplace, snoring problems are increasing.

Started in 1991, the British Snoring and Sleep Apnea Association exists to provide useful information for snorers and their bed partners in order to help them deal with the snoring problem that’s been troubling their partnership, sleep and basically their lives.

In 2011, the organization was given recognition by …

Programmable Logic Advances Quickly

September 20th, 2014

plaAccording to Clive McCarthy, Altera’s vice president of development engineering, the arrays may represent a new category of programmable logic. Previous FPGA architectures tended to fall into two categories–either fine-grained for high logic utilization or coarse-grained for high performance. FLEX arrays combine the two (Fig. 1). Within each array are logic-array blocks (LABs) that form the coarse grains. However, each LAB can be subdivided further into eight logic elements (LEs), with each LE (the fine grains) containing sequential and combinatorial logic.

The combinatorial logic in each LE consists of a 4-input lookup table and a cascade input and output. The lookup table can implement any function of four variables in 5 ns. Also, the LE’s sequential portion contains a configurable flip-flop with …

Fevers: The Good And Bad

September 17th, 2014

ftgabEverybody’s had it – that hot, burning feeling that can go along with a headache and body aches, followed the next minute by a chill. Altogether, you feel just plain miserable.

If you were living in the second century, or maybe even as late as the 1700s, you would say your body humors were out of balance and the fire in your heart was trying to burn up and offending humor. Today you would just complain, “I think I’ve got a fever.”

The fire that early physicians imagined to be in the heart of every human being was no poetic expression. They took it literally – visualizing an actual fire in the organ that pumps blood throughout the human body. It was …

Environmental Studies Courses Worth The Challenge

September 13th, 2014

escPop quiz: What would you rather be doing? Sitting in a crowded lecture hall lost in the drone of a professor delineating the finer points of pH testing, trophic levels and sediment in aquatic ecosystems or pulling on some waders and splashing into a campus creek to test it for acid rain?

Question number two: Where in the course catalogue would you find a class in which you learn how to make a solar-heated shower?

If you’re an environmental science student at Dickinson College in Carlisle, Pa., you’d be monitoring streams, analyzing data and putting out a newsletter about acid precipitation problems in the state rather than spending much of your time in the classroom. And if you’re a student at Humboldt …

The Advantages Of Using Search Engine Optimization As A Marketing Strategy

August 20th, 2014

seomSearch engine optimization is an internet marketing strategy used by online businessmen.  In order for an online business to attract customers, it must be seen first by people who search for products and services in the internet and the best way to be seen easily is by appearing first in the search results of Google, Bing, or Yahoo.

Here are some of the advantages of using search engine optimization to market your products or services. First, your business name will be seen on the first page of the search engine results. The internet users tend to click first the links that appear on page one so they will see your business easily. Second, you will be able to increase …

Make Those Batteries Roll!

June 5th, 2014

brLoad testing a battery will give a good indication of its true value for a given application. Batteries used to supply power for high current demand applications like flashlights, digital cameras, and other current-hungry devices should be load tested at or near their operating current level. The actual operating current level can be checked and matched with a fixed resistive load; however, in many applications this is not easy.

A good average resistive load for AA batteries in high current applications is a 1.5-ohm, 5-watt resistor. (See Fig. 1.) This load can be a single 1.5-ohm resistor or ten 15-ohm, 1/2-watt resistors in parallel. For less power-hungry applications, a 10-ohm resistor will do for comparing one brand to another. Lighter …

Avoiding The 21st Century By Hating Computers

May 20th, 2014

hcOf course, our eight-year-old minds thought she was an old lady and, maybe, even a little off her rocker. Well, guess what, Mrs. McKissick? It’s true! This wonder you were describing has arrived. It is called the personal computer, and at the ripe old age of thirty-eight, I have finally decided that “if you can’t beat ‘em…join ‘em.”

My PC is the fourth in our household. My needs had to follow our four-years-old’s yearning to play her Barble and Blue’s Clues’ games, even though Daddy was home at night laying claim to his own Compaq Presario 4880-Series P-II 400. Hers was our third investment, a Pentium 120. However, It didn’t take long to figure out that Daddy’s computer is faster; so she …

Benchmarking Video Cards – The Details

May 7th, 2014

vgaA more comprehensive set of video benchmarks is available from a company with the unlikely name of MadOnion. Previously called FutureMark, this vendor produces a professional-level set of DirectX 8-based video benchmarks called the 3DMark200l Benchmark. A free copy similar to the one we use is available for downloading from FutureMark’s Web site (www.futuremark.com), if you have the time. It’s a 40-MB file, so even with a broadband Internet connection it takes a while to download. The Professional version of 3DMark200l adds a few features, like the Result Browser that enables you to examine several cards’ results sideby-side.

The 3DMark2001 Benchmark does have a frame-rate test. In fact, it has several, with “demo” games of varying complexity programmed to simulate …

Building A Shortwave Converter

March 30th, 2014

bascThe converter circuit consists of a Hartley oscillator and a mixer. In this circuit, the frequency of the incoming signal is combined with the signal from the oscillator in the mixer. The signals are heterodyned, and an intermediate frequency is produced. For example, if the incoming signal was 6600 kHz and the oscillator was set at 5000 kHz, the intermediate frequencies would be 1600 and 11600. The lower frequency intermediate signal would now be in the frequency range for any AM radio to receive. Using this method, any high-frequency signal can convert to a lower frequency. If the AM radio was tuned to 1600 kHz, it would pick up the 1600 kHz intermediate frequency and reject the other.

The oscillator was designed …
