Mechanical Challenges Rise With Heterogeneous Integration


Companies integrating multiple chips or chiplets into a package will need to address structural and other mechanical engineering issues, but gaps in the design tools, new materials and interconnect technologies, and a shortage of expertise are making it difficult to address those issues. Throughout most of the history of the semiconductors, few people outside of foundries worried about struc... » read more

True 3D Is Much Tougher Than 2.5D


Creating real 3D designs is proving to be much more complex and difficult than 2.5D, requiring significant innovation in both technology and tools. While there has been much discussion about 3D designs, there are multiple interpretations about what 3D entails. This is more than just semantics, however, because each packaging option requires different design approaches and technologies. And a... » read more

The Race Toward Mixed-Foundry Chiplets


Creating chiplets with as much flexibility as possible has captured the imagination of the semiconductor ecosystem, but how heterogeneous integration of chiplets from different foundries will play out remains unclear. Many companies in the semiconductor ecosystem are still figuring out how they will fit into this heterogeneous chiplet world and what issues they will need to solve. While near... » read more

Managing EDA’s Rapid Growth Expectations


The EDA industry has been doing very well recently, but how long this run will continue is a matter of debate. EDA is an industry ripe for disruption due to rapid changes in chip architectures, end markets, and a long list of new technologies. In addition, recent geopolitical tensions are bringing a lot more attention to this small sector upon which the whole semiconductor industry rests. De... » read more

Startup Funding: February 2023


The cost of borrowing is going up, but investors continued to pour money into the chip industry in February. Collectively, 132 companies raised more than $4.5 billion last month. One of the big beneficiaries was quantum computing, with nine companies drawing a total of more than $500 million. The bulk of that went to a quantum software and services company spun out of Alphabet, but plenty wa... » read more

How To Build Resilience Into Chips


Disaggregating chips into specialized processors, memories, and architectures is becoming necessary for continued improvements in performance and power, but it's also contributing to unusual and often unpredictable errors in hardware that are extremely difficult to find. The sources of those errors can include anything from timing errors in a particular sequence, to gaps in bonds between chi... » read more

Taming Corner Explosion In Complex Chips


There is a tenuous balance between the number of corners a design team must consider, the cost of analysis, and the margins they insert to deal with them, but that tradeoff is becoming a lot more difficult. If too many corners of a chip are explored, it might never see production. If not enough corners are explored, it could reduce yield. And if too much margin is added, the device may not be c... » read more

Leveraging Chip Data To Improve Productivity


The semiconductor ecosystem is scrambling to use data more effectively in order to increase the productivity of design teams, improve yield in the fab, and ultimately increase reliability of systems in the field. Data collection, analysis, and utilization is at the center of all these efforts and more. Data can be collected at every point in the design-through-manufacturing flow and into the f... » read more

Dealing With Performance Bottlenecks In SoCs


A surge in the amount of data that SoCs need to process is bogging down performance, and while the processors themselves can handle that influx, memory and communication bandwidth are straining. The question now is what can be done about it. The gap between memory and CPU bandwidth — the so-called memory wall — is well documented and definitely not a new problem. But it has not gone away... » read more

Power Issues Causing More Respins At 7nm And Below


Power consumption has been a major design consideration for some time, but it is far from being a solved issue. In fact, an increasing number of designs have a plethora of power-related problems, and those problems are getting worse in new chip designs. Many designs today are power-limited — or perhaps more accurately stated, thermal-limited. A chip only can consume as much power as it is ... » read more
