Short-Circuit Ruggedness In SiC MOSFETs


Trench-based silicon carbide power MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) represent a dramatic improvement in the Figure of Merit (FOM) values of power conversion switching devices. As a result, outstanding system performance is achieved, enabling higher efficiency, power density, and reduced system cost for many applications. Today, for major target applications for S... » read more

The Importance Of Aging Simulation In IC Design


Electronics reliability has been an important quality criterion in the automotive sector and in industrial automation for years. Electronics in this sector have to achieve product lifetimes of 10+ years under partially harsh environmental conditions. But the reliability of electronics is also becoming more important in other fields. For example, end customers now keep consumer products longer, ... » read more

Reliable And Efficient Compact Models For Scalable MTJ Simulation


By Fernando García Redondo, Pranay Prabhat, and Mudit Bhargava Since its discovery in 1975, Tunnel-Magneto-Resistance (TMR) has been actively investigated. From the 2000s, advances in process technologies have made the miniaturization of Magnetic Random Access Memories (MRAMs) based on TMR devices possible, together with integration into traditional CMOS processes. Introducing magneti... » read more

Integrated Ethernet PCS And PHY IP For 400G/800G Hyperscale Data Centers


Ethernet has become the primary network protocol of choice for the required server-to-server communication in hyperscale data centers, as it allows hyperscalers to disaggregate network switches and install their software operating systems independently. Ethernet enables cost-effective, dense, open switches and networking technologies which reduce cost/power per bit with transistor scaling. Ethe... » read more

The Shortest Path Deception


When manufacturing, assembling, and using integrated circuit (IC) chips, the electrostatic discharge (ESD) caused by accumulated static can damage the IC circuitry if the circuit is not properly protected [1]. To prevent such damage, ESD protection devices are designed into the circuitry such that they will create a low impedance path that limits the peak voltage and current by diverting excess... » read more

The Next Generation Of General-Purpose Compute At Hot Chips


At the recent HOT CHIPS, the first day opened with the chips that you first think of when you hear the word processor. These are the next generation of chips from the likes of Intel, AMD, and IBM. There were lots of other chips too, such as Arm's Neoverse N2, and NVIDIA's new data-processing unit (DPU), or AMD's next-generation graphics architecture. But for this post, anyway, I'm going to focu... » read more

On the Road To Higher Memory Bandwidth


In the decade since HBM was first announced, we’ve seen two-and-a-half generations of the standard come to market. HBM’s “wide and slow” architecture debuted first at a data rate of 1 gigabit per second (Gbps) running over a 1024-bit wide interface. The product of that data rate and that interface width provided a bandwidth of 128 gigabytes per second (GB/s). In 2016, HBM2 doubled the s... » read more

The Impact Of Multiphysics On Production Electronic Design


For many electronic design professionals, it has become clear that the industry is transitioning through an inflection point that is shifting some of the ground rules of design. The increase in the speed and integration density in today’s systems are blurring the lines between chip design and traditional board or system design. This finds its fullest expression in multi-die, 3D integrated ... » read more

The “Natively Flexible” Processor Has Arrived: Here’s What We Need To Make It Mainstream


The microprocessor is one of history’s pivotal inventions, ranking in influence with breakthroughs such as the wheel, the transistor, and the printing press. There is no escaping their popularity or usefulness either: with tens of billions of processors produced each year they have revolutionized industries such as health care, media, retail, transportation, and of course information manageme... » read more

Now You Can Automate Latch-Up Verification For 2.5/3D Technologies


Latch-up is modeled as a short circuit (low-impedance path) that can occur in an integrated circuit (IC). It may lead to destruction due to over-current resulting from interactions between parasitic devices (PNP and NPN). To protect against latch-up conditions, there are two key types of latch-up design rules—fundamental and advanced [1,2]. Fundamental rules are the local latch-up design r... » read more
