Simulating The Hyperloop


When SpaceX held the first Hyperloop Design Weekend Competition in Texas in January 2016, a team of five students from the Universitat Politècnica de València (UPV) in Spain, calling themselves Hyperloop UPV, won awards for Best Overall Concept Design and Best Propulsion System. The overall concept was to use magnetic levitation to give their Hyperloop vehicle a frictionless ride through t... » read more

Elasticity Without Compromise


At the dawn of the twenty-first century, the available RAM on a physical machine dictated, and ultimately limited, the size of designs that Ansys HFSS could simulate. This prompted engineers to buy incredibly expensive pieces of hardware — well into the six figures — to solve their most challenging problems. By necessity, engineers learned to “divide and conquer” their largest, most ... » read more

Electronics For Quantum Communications


Our secure digital communications so far have functioned on the principle of key-based encryption. This involves generating a key of appropriate length, which is then used to encrypt the data. Because distributing the keys is difficult, the keys are reused rather than regularly generating new ones. The regular use of the keys opens up the encryption process to attacks by mathematical methods... » read more

Customizing Low-Power Platforms Using UPF Dynamic Properties


Low power design and verification engineers need a way to continuously probe various dynamic properties of UPF objects in order to monitor the current state of a verification strategy and utilize that information to develop custom low-power verification environments. Unfortunately, there hasn’t been a reliable, formalized way to do this. Since availability of the dynamic properties of unif... » read more

Building Billions Of Batteryless Devices


Later this month, Arm will celebrate its 30 year anniversary and the engineering milestones that have resulted in more than 180 billion Arm-based chips being shipped in everything from sensors to smartphones to the world’s fastest supercomputer. In each of these cases, much of Arm’s success has been in our dedication to delivering the highest performance per watt. But while Arm may ha... » read more

The Expanding Universe Of MIPI Applications


It’s hard to imagine today, but there was a time when mobile phones had no cameras and displays were tiny monochrome LCDs capable of displaying a phone number and not much more. The iconic Nokia 3310 announced Sept. 1, 2000, had an 84 x 48 pixel monochrome display and went on to sell 126 million units worldwide. You may still have one in your junk drawer. By the time of the original iPhone... » read more

Design For Manufacturing Best Practices


Manufacturing issues are one of the top reasons that we see warranty returns and loss of market share in the electronics industry. Issues like supply chain failures and printed circuit board assembly (PCBA) production challenges related to design can lead to irreparable damage to a brand’s reputation. It is therefore critical that companies have a design for manufacturability (DfM) protocol i... » read more

Arm Goes For Performance


At the recent Linley Processor Conference, Arm presented two processors. This was regarded as so confidential that the original pre-conference version of the presentations didn't contain the Arm one, even though that pdf was only put online about an hour before. But most of the outline of what they presented they already talked about in May, a few months ago. I said recently that this seem... » read more

The Challenge Of Balancing Performance And Accuracy For Advanced Node Timing Signoff


As process nodes shrink, complexity, cost and overall risk expand. Process variability that once was once acceptable now becomes a critical item as operating voltage decreases. Simply adding design margin makes the chip non-competitive. Physical effects that were once ignored now become critical as well. The impact of interconnect can no longer be modeled based on simple circuit topology. Layou... » read more

GDDR6 Memory For Life On The Edge


With the torrid growth in data traffic, it is unsurprising that the number of hyperscale data centers has grown apace. According to analysts at the Synergy Research Group, in July of this year there were 541 hyperscale data centers worldwide. That represents a doubling in the number since 2015. Even more striking, there are an additional 176 in the pipeline, so the breakneck growth in hyperscal... » read more
