Strain, Stress In Advanced Packages Drives New Design Approaches


Thermal and mechanical stresses are creating significant challenges in heterogeneous chiplet assemblies, increasing the time and cost required to work through all the possible physical effects, dependencies, and interactions, and driving demand for new tools. Unlike in the past, when various components were crammed into a planar SoC on a relatively thick substrate, the new substrates are bei... » read more

Improving Verification Performance


Without methodology improvements, verification teams would not be able keep up with the growing complexity and breadth of the tasks assigned to them. Tools alone will not provide the answer. The magnitude of the verification task continues to outpace the tools, forcing design teams to seek out better ways to intermix and utilize the tools that are available. But as verification teams take on... » read more

SLM Evolves Into Critical Aspect Of Chip Design And Operation


Silicon lifecycle management has evolved greatly in the past five years, moving from novel concept to a key part of design flows at industry leaders such as NVIDIA, Amazon Web Services, Ericsson, and others. Along with becoming a major focus for companies developing semiconductors, the use cases have expanded. While initially focused on post-silicon insights, SLM has expanded to cover the en... » read more

RISC-V Profiles Help Conformance


Experts At The Table: What's needed to be able to trust that a RISC-V implementation will work as expected across multiple designs using standard OSes. Semiconductor Engineering discussed the issue with John Min, vice president of customer service at Arteris; Zdeněk Přikryl, CTO of Codasip; Neil Hand, director of marketing at Siemens EDA (at the time of this discussion); Frank Schirrmeist... » read more

Baby Steps Toward 3D DRAM


Flash memory has made incredible capacity strides thanks to monolithic 3D processing enabled by the stacking of more than 200 layers, which is on its way to 1.000 layers in future generations.[1] But the equally important DRAM has achieved a similar manufacturable 3D architecture. The need for a sufficiently large means of storing charge — such as a capacitor — has proved elusive. Severa... » read more

Navigating Increased Complexity In Advanced Packaging


As chips evolve toward stacked, heterogeneous assemblies and adopt more complex materials, engineers are grappling with new and often less predictable sources of variation. This is redefining what it means to achieve precision, forcing companies to rethink everything from process control and in-line metrology to materials selection and multi-level testing. These assemblies are the result of ... » read more

Challenges In Powering Electrification With GaN And SiC


The wish list of device properties that designers of power management systems would like to have is lengthy, but no single material is yet sufficient for the full range of power control applications. For control transistors to handle power surges, breakdown voltages should be at least triple the expected operating voltage — 1.2 kilovolts or more for many electric vehicle applications, and ... » read more

Shortcutting Graduates’ Path To Productivity In Manufacturing And Test


Manufacturing, test, assembly, and analytics companies are finding unique ways to engage with universities in an effort to shore up the talent pipeline. The industry is recruiting graduates from universities across the U.S. while partnering with local institutes to serve specific needs. Industry/university co-operation includes: Mapping job descriptions Providing curricula frameworks... » read more

Is In-Memory Compute Still Alive?


In-memory computing (IMC) has had a rough go, with the most visible attempt at commercialization falling short. And while some companies have pivoted to digital and others have outright abandoned the technology, developers are still trying to make analog IMC a success. There is disagreement regarding the benefits of IMC (also called compute-in-memory, or CIM). Some say it’s all about reduc... » read more

Chiplet Interconnects Add Power And Signal Integrity Issues


The flexibility and scalability offered by chiplets make them an increasingly attractive choice over planar SoCs, but the rollout of increasingly heterogeneous assemblies adds a variety of new challenges around the processing and movement of data. Nearly all of the chiplets in use today were designed in-house by large systems companies and IDMs. Going forward, third-party chiplets will begin... » read more
