BAM BLOG: De-mystifying semiconductor IP - Blog

March 19, 2014
Before & After Market (BAM) Blog: Nowadays, it’s called IP. Decades ago, it was just called software. By either name, it is the programming inside a chip that makes the chip unique. Software/IP is also a big factor in product lifecycle management (PLM).

BAM Blog: chip makers respond to mil-spec market pressures - Blog

February 24, 2014
Before & AfterMarket (BAM) Blog: The military market is renowned for developing and implementing the most advanced technology available. However, a device that’s central to most of this technology – the semiconductor – is lagging in the military-market design space.

BAM Blog: How packaging issues accelerate EOL - Blog

February 06, 2014
Before & AfterMarket (BAM) Blog: Nobody likes to be duped. Anyone who has ever bought a “designer” handbag on the street at a huge discount quickly figures out the deal was too good to be true. Something that looked genuine on the outside turns out to be fake.

BAM BLOG: When buying based on cost doesn?t make sense - Blog

January 15, 2014
Before & AfterMarket (BAM) Blog: Most of the public debate about onshore versus offshore manufacturing has to do with the cost of production and domestic-market competitiveness. But in many cases, the debate should not be exclusively about cost – it should be about trust.

BAM Blog: obsoleted semiconductors and DO-254 - Blog

December 18, 2013
Before and Aftermarket (BAM) Blog: As semiconductors become more and more complex, guaranteeing that they can still function correctly in safety-critical applications is proving increasingly difficult; and in many cases, system testing to assure correct operation under all foreseeable equipment operating conditions is often impossible. The avionics industry has recognized this problem and introduced guidelines for manufacturers to follow to overcome the testing dilemma.

BAM Blog: heads up on components availability for heads-up displays - Blog

November 27, 2013
BEFORE & AFTER MARKET (BAM) BLOG: Jet fighters and the family car will have several things in common in the near future. When a disruptive technology is developed, prior generations of similar technologies are significantly impacted. In the consumer market, customers can generally adopt new technologies rapidly if the price point is right. Conversely, higher-value equipment with long operating life times does not have this luxury. Manufacturers of prior generations of military, space, and aerospace equipment may find their supply chain disrupted as cost-conscious vendors adapt to a more volatile market cycle.

John Rynearson named first VITA Hall of Fame inductee - Blog

November 20, 2013
John Rynearson, technical director of VITA, is the first person to be inducted into the newly created VITA Technologies Hall of Fame. The news took him by pleasant surprise, announced during today’s VITA Standards Organization (VSO) meeting in Scottsdale, AZ, in front of his friends and peers in the industry. After the announcement was given by John McHale, editorial director of Military Embedded Systems magazine, the room filled with applause and congratulations.

BAM BLOG: Counterfeits: the 2,000 versus 200 Equation - Blog

November 13, 2013
Before & AfterMarket Blog (BAM). At first glance, having 2,000 component suppliers to choose from -- versus 200 – is a good thing. Competition drives down prices and component selection appears bountiful. In the electronics supply chain, though, things don’t always work that way. In fact, the “2,000 vs. 200” equation is downright dangerous. Almost any vendor can sell a component, but not all vendors are authorized to do so. This is a big distinction.

Six customized computers myths that you should know - Blog

November 04, 2013
One of the most common problems executives face is making business decisions about technologies with which they are not familiar. As they survey the crowded marketplace, corporate leaders often rely on information from self-interested vendors, or so-called conventional wisdom.

Collecting semiconductor products - Blog

October 21, 2013
NEWBURYPORT, MA. I've found where they put the Lost Ark at the end of "Raiders of the Lost Ark" -- it's in an aftermarket semiconductor warehouse in Newburyport, MA. Seriously, Rochester Electronics has a storage area for products going back decades that is eerily similar to the one in the movie (see photo).

Designing OpenVPX systems to support Gen3 >10 Gbaud signaling - Blog

September 30, 2013
Signal Integrity (SI) is becoming an increasingly critical consideration for designers of OpenVPX systems. While system integrators first confronted some SI issues as the embedded industry made the performance advance from Gen1 at 3.125 Gbaud to Gen2 at 6.25 Gbaud signaling, the current transition to Gen3 >10 Gbaud signaling rates, nearly doubling the bandwidth of Gen2 OpenVPX, requires a significant increase in the level of tools, capability, expertise, and know-how to ensure successful design and implementation of a robust latest generation, OpenVPX system.

Ada Watch: Choosing the right Ada subset for strong static guarantees - Blog

August 13, 2013
While Ada offers many features that act as safety guards at run time, by raising exceptions when a violation is detected, some of these features may be too complex to guarantee a safe execution before the program is run. This is the case for example of pointers, which may be used to create arbitrarily complex shared data structures in memory. SPARK is a subset of Ada that forbids these features, most notably pointers, in order to be able to provide strong guarantees at compile time. A preview of the next revision of SPARK called SPARK 2014 is already available, as well as the associated verification tools.
