Looking Back at Board Test

Printed circuit board testing has been around as long as printed circuit boards, also known as printed circuit assemblies and printed wiring boards. PCB technology started in the early 20th century with Thomas Edison and other inventors. As boards shrink to fit inside wearable gadgets and other products with compact form factors, PCB test equipment vendors are addressing new challenges. Boar... » read more

A Brief History of Test

The history of semiconductor test systems is the subject of this blog post. We’ll turn to printed circuit board testing at another time. Boston-based Teradyne sold its D133 diode tester to Raytheon in 1961. Five years later, it introduced the J259 integrated circuit tester, which had a minicomputer to run the test programs. For many, this marks the beginning of automatic (or automated) tes... » read more

Logic Analyzers Never Die

Logic analyzers, long a mainstay of chip design, are finding new demand for IoT devices—and frequently in different forms than in the past. Once associated with big, bulky benchtop instruments, this technology has evolved significantly over the past 40 years. In some cases it has been moved into software, where the measurement results are more likely to be viewed upon a laptop screen or a ... » read more

The Week In Review: Design/IoT

Numbers EDA sales dropped 1.9% in Q4 of 2015, following a spectacular run of 23 consecutive quarters of solid growth, according to EDAC. For the year, the EDA and IP industry posted 5% growth. At the same time, IP revenue grew 9.2% to $702.2 million, making it the first time ever that IP surpassed CAE revenue. Services revenue also grew 5.4% year over year to 107.1 million. A new report f... » read more

3 Ways To Reload Moore’s Law

The electronics revolution has been enabled because the cost and power per transistor has decreased 30% per year for the last 30 years — a fact usually associated with Moore's Law. This has been accomplished by simply reducing the transistor size while offsetting increased costs of equipment and mask levels, and by increased productivity from improved yield, throughput and wafer size. This... » read more

Does Fast Simulation Help Debug Productivity?

It is nice when a reporter manages to get the scoop of the century, and that was the case at a lunch panel hosted by [getentity id="22032" e_name="Cadence"] at the recent Design and Verification Conference (DVCon) in Santa Clara, CA. Brian Bailey, technology editor for Semiconductor Engineer was the moderator for the panel and broke the news to the crowd. Cadence had developed a logic [getkc id... » read more

What Exactly Is The IoT?

The Internet of Things has drawn its share of attention. It has been overhyped, derided, and in some cases dismissed as the Internet of Silos. But the idea persists, and it’s catching on. So how much substance is there behind the hype? Best guess: Quite a bit. “We do see this as being a fast-growing market,” said Jim Feldhan, president of Semico Research. “The number of connected ... » read more

Patents Under Scrutiny

After years of complaints by high-tech companies that the U.S. patent system is misused, too slow or completely outdated, patent attorneys are about to get their day in court. The U.S. Supreme Court has agreed to review an appeal between Alice Corp., an electronic marketplace for trading IP, and CLS Bank International, involving what kinds of inventions can be patented, according to the Supr... » read more

The Week In Review: System-Level Design

The big buzz at this year’s CES is around wearable computing, according to Gartner, and the big drivers will be fitness and digital health. The firm believes wearable electronics will be peripherals to smartphones, which will provide connectivity to store and analyze biodata. Hewlett-Packard plans to cut 34,000 employees by the end of this year, or roughly 11% of its workforce, according t... » read more

Formal Verification Comes Of Age

By Ann Steffora Mutschler Formal verification technology, also known as formal property checking, has been in existence since the early 1990s. Still, it’s only in the past five years that it has made big strides in the last five years in terms of the capacity of the technology to handle bigger pieces of a design, leveraging advancements in computing as well as improvements to the algor... » read more
