Many Chiplet Challenges Ahead


Over the past couple of months, Semiconductor Engineering has looked into several aspects of 2.5D and 3D system design, the emerging standards and steps that the industry is taking to make this more broadly adopted. This final article focuses on the potential problems and what remains to be addressed before the technology becomes sustainable to the mass market. Advanced packaging is seen as ... » read more

Interconnects In A Domain-Specific World


Moving data around is probably the least interesting aspect of system design, but it is one of three legs that defines the key performance indicators (KPI) for a system. Computation, memory, and interconnect all need to be balanced. Otherwise, resources are wasted and performance is lost. The problem is that the interconnect is rarely seen as a contributor to system functionality. It is seen... » read more

Stuck In A Rut


In the DVCon panel session about open-source verification, the first part of which has been published along with this blog, you will read about a fiery debate between the panelists. This is regarding the ability of the EDA industry to innovate. On one side is the accusation that there has been no real innovation since 1988. On the other side, there have been fantastic advances have been made th... » read more

Verification In The Open Source Era


Experts at the Table: Semiconductor Engineering sat down to discuss what open source verification means today and what it should evolve into, with Jean-Marie Brunet, senior director for the Emulation Division at Siemens EDA; Ashish Darbari, CEO of Axiomise; Simon Davidmann, CEO of Imperas Software; Serge Leef, program manager in the Microsystems Technology Office at DARPA; Tao Liu, staff hardwa... » read more

Waiting For Chiplet Standards


The need and desire for chiplets is increasing, but for most companies that shift will happen slowly until proven standards are in place. Interoperability and compatibility depend on many layers and segments of the supply chain coming to agreement. Unfortunately, fragmented industry requirements may lead to a plethora of solutions. Standards always have enabled increasing specialization. ... » read more

Designing 2.5D Systems


As more designs hit the reticle limit, or suffer from decreasing yield, migrating to 2.5D designs may provide a path forward. But this kind of advanced packaging also comes with some additional challenges. How you adapt and change your design team may be determined by where your focus has been in the past, or what you are trying to achieve. There are business, organizational, and technical c... » read more

Domain-Specific Memory


Domain-specific computing may be all the rage, but it is avoiding the real problem. The bigger concern is the memories that throttle processor performance, consume more power, and take up the most chip area. Memories need to break free from the rigid structures preferred by existing software. When algorithms and memory are designed together, improvements in performance are significant and pr... » read more

Chiplets For The Masses


Chiplets are a compelling technology, but so far they are available only to a select few players in the industry. That's changing, and the industry has taken little steps to get there, but timing for when you will be able to buy a chiplet to integrate into your system remains uncertain. While new fabrication nodes continue to be developed, scaling is coming to an end, be it for physical or e... » read more

The Single Greatest Opportunity For Open Source


Next week, I will be moderating a panel at the virtual DVCon on the subject of open-source verification. I thought it would be good to advertise the event on LinkedIn to see if anyone wanted to send me well-structured questions for the panelists. What happened surprised me a little because the discussions almost exclusively went to the need for open-source verification tools. In my opinion, the... » read more

Firmware Skills Shortage


Good hardware without good software is a waste of silicon, but with so many new processors and accelerator architectures being created, and so many new skills required, companies are finding it hard to hire enough engineers with low-level software expertise to satisfy the demand. Writing compilers, mappers and optimization software does not have the same level of pizazz as developing new AI ... » read more
