Advantages to using NoCs in SoC design are well documented: reduced routing congestion, better performance than crossbars, improved optimization and reuse of IP, strategies for system power management, and so on. What happens when NoCs move into FPGAs, or more accurately the SoC variant combining ARM cores with programmable… Read More



Granite River Labs and TSMC Expand Agreement
For several years now, TSMC has run increasingly sophisticated IP validation. Ramping a new process as a foundry requires a number of things to all come together almost simultaneously: the process, of course, and some designs to run and start to recover the huge capital investment a modern fab entails. With many SoCs having over… Read More
Xilinx UltraScale gives you 25% more packing than you know who…
Coke with no ice. You see I am not cheap, or even frugal but a good steward. One of the things that I hate the most is waste. You know lights on in every room, door open during winter and driving 25 miles to save a dollar on gas.
One will notice fairly quickly that with Xilinx UltraScale 20nm FPGAs coupled with the new-fangled analytical … Read More
Silicon Measurement Data Gives Insights to Using Metal Fill With Inductors
Metal fill requirements for inductors are now a fact of life. Fill has long been seen as detrimental to device performance due to parasitic capacitance. The necessity of fill arises from the need to ensure planarization of dielectric layers by using chemical mechanical polishing. Without adequate fill, areas of the chip can suffer… Read More
Broadcom Internet of Things
One of the perks of blogging here is being able to get a press invitation to lots of events, often in interesting locations I never even knew existed. Tonight it was a Broadcom event in SPUR here in San Francisco. The evening was about the Internet of Things (IoT). Everyone knows that IoT is sort of hype, but it is also a real opportunity.… Read More
Do you check your circuit DC stability?
Most analog designers are aware of loops stability. In most cases, stability is understood as AC stability, the goal is ensuring enough phase (gain) margin so as to avoid the loop to enter oscillation. But prior to studying AC stability, DC stability should be questioned. What is that DC stability only few people think of?… Read More
Opting for ARM software scalability
Behind much of the success of ARM architecture is a scalable software model, where in theory the same code runs on the smallest member of the family to the largest. In practice, there are profiles, and a variety of hardware execution units, and resource constraints in low power scenarios that enter the picture. As a result, operating… Read More
Mentor: It’s All About Cars
Mentor’s results came out last week. They were good. Wally opened the call:Thanks. Once again results for Mentor Graphics in the quarter exceeded our guidance. Revenue of $260.2 million and non-GAAP earnings per share of $0.23, were ahead of our guidance of $250 million and $0.15 earnings per share. Strength in bookings… Read More
Secure at any IoT deed
In his classic book “Unsafe at Any Speed”, Ralph Nader assailed the auto industry and their approach to styling and cost efficiency at the expense of safety during the 1960s. He squared up on perceived defects in the Chevrolet Corvair, but extended his view to wider issues such as tire inflation ratings favoring passenger comfort… Read More
The EDA Ice Bucket Challenge Just Got Real!
Raising four children is no easy task, believe me. My beautiful wife and I always felt it was important to foster the charitable side of our children by volunteering at the food bank, cleaning up local waterways, and other activities we could do as a family. To be clear, that is why my family did the ALS Ice Bucket Challenge.
“It is amazing… Read More
