I was trying to find the comment one of my counterparts here made eight months ago that given the cash burn rate, Nokia would be out of business in eight months, so I could gloat a bit. Bzzzzzzt – cash position actually increased in 1Q13. The numbers tell a painful story about a company on a difficult diet to survive, one that analysts… Read More

Power integrity: ground, and other fairy tales
Ground. It’s that little downward-pointing triangle that somehow works miracles on every schematic. It looks very simple until one has to tackle modern power distribution network (PDN) design on a board with high speed and high power draw components, and you soon discover ground is a complicated fairy tale with a lot of influences.… Read More
Signal integrity: more than just SerDes analysis
When Cadence acquired Sigrity in 2012, two motives were involved: get more competitive in state of the art signal integrity analysis, and grab a foothold into the other vendor’s PCB flows in an area that is developing as a real sore spot for digital designers.
Just as the days where PCB tape-out meant actually using tape are over, … Read More
In compliance we trust, for integration we verify
So, you dropped that piece of complex IP you just licensed into an SoC design, and now it is time to fire up the simulator. How do you verify that it actually works in your design? If you didn’t get verification IP (VIP) with the functional IP, it might be a really long day.
Compliance checking something like a PCIe interface block is a … Read More
Plotting to take over the time-domain only world
The state machine nature of many digital designs has made time-domain debugging the favorite tool for most designers. We provide a set of inputs, data gets clocked in, and a set of outputs appears. We look for specific patterns in parallel paths, or sequences on serial lines.… Read More
When the lines on the roadmap get closer together
Tech aficionados love roadmaps. The confidence a roadmap instills – whether using tangible evidence or just a good story – can be priceless. Decisions on “the next big thing”, sometimes years and a lot of uncertain advancements away, hinge on the ability of a technology marketing team to define and communicate a roadmap.
Any roadmap… Read More
Shrinking audio creates issues and opportunities
There is a lot more to sound than meets the ear, and there a vast number of ways to deliver an audio experience. I recently trashed my gaming headset, replacing it with a Samson C03U mic and Audio-Technica ATH-PRO700MK2 headphones. It’s a huge upgrade, especially for podcasting, and I admit I was also motivated by research into digital… Read More
Is debugging a task, or a continuous process?
Early in my so-called EE career, I sat in a workshop led by the director of quality for the Ford truck plant in Louisville, KY, where “Quality is Job #1.” At that time, they were gaining experience in electronic control modules (ECMs) for fuel efficiency and emissions control. Who better to transfer the secrets of Crosby and Deming… Read More
SHIELDing the Android GPU developer in C
Repeat after me: SoCs are paperweights if they can’t be programmed. Succeeding with a new part today means supporting a robust developer program to attract and engage as many creatives as possible. NVIDIA has teamed up with Mentor Graphics in just such an adventure. If you read just the press release, you may have missed the real … Read More
UVM: Lowering the barrier to IP reuse
One of my acquaintances at Intel must have some of the same viewing habits I do, based on a recent Tweet he sent. He was probably watching “The Men Who Built America” on the History Channel and thinking as I have a lot recently about how the captains of industry managed to drive ideas to monopolies in the late 1800s and early 1900s.
