DRAM Choices Are Suddenly Much More Complicated


Chipmakers are beginning to incorporate multiple types and flavors of DRAM in the same advanced package, setting the stage for increasingly distributed memory but significantly more complex designs. Despite years of predictions that DRAM would be replaced by other types of memory, it remains an essential component in nearly all computing. Rather than fading away, its footprint is increasing,... » read more

Is Your Voltage Drop Flow Obsolete?


Voltage drop at advanced nodes is a deadly serious problem that has become unmanageable with the methodologies used by most chip designers today. This article will cover the reasons why power integrity has risen to a top-of-mind concern and why it has become almost impossible for today’s EDA tools to measure and fix it. We will then look at some radical methodology rethinking that is needed t... » read more

Chip Industry Week In Review


By Jesse Allen, Gregory Haley, and Liz Allan Bosch, Infineon, and NXP were cleared in Germany to each acquire 10% of the European Semiconductor Manufacturing Co. (ESMC), established by TSMC, solidifying the supply chain against future shortages, particularly for automotive chips. “ESMC intends to build and operate another large semiconductor factory in Dresden, in which the three Europ... » read more

Flipping Processor Design On Its Head


AI is changing processor design in fundamental ways, combining customized processing elements for specific AI workloads with more traditional processors for other tasks. But the tradeoffs are increasingly confusing, complex, and challenging to manage. For example, workloads can change faster than the time it takes to churn out customized designs. In addition, the AI-specific processes may ex... » read more

An Entangled Heterarchy


For decades, a form of structural hierarchy has been the principal means of handling complexity in chip design. It's not always perfect, and there is no ideal way in which to divide and conquer because that would need to focus on the analysis being performed. In fact, most systems can be viewed from a variety of different hierarchies, equally correct, and together forming a heterarchy. The e... » read more

3D Heterogenous Integration: Design And Verification Challenges


Next-generation semiconductor products increasingly rely on vertical integration technologies to drive system density, speed, and yield improvement. Due to the increased coupling effects across multiple physics, co-simulation and co-analysis of these phenomena are critical for a robust chip-package-system design. Advanced 2.5D/3D-IC systems are constructed with multiple dice, interposers, packa... » read more

Blog Review: Nov. 8


Siemens' Todd Westerhoff takes a look at the three stages of power integrity analysis for PCBs, challenges to board-level signal integrity, and best practices for getting the most accurate estimate of design performance. Synopsys' William Ruby provides a brief overview of the evolution of low-power design techniques and finds opportunities to reduce power and to make chip designs more energy... » read more

Chip Industry Week In Review


By Susan Rambo, Gregory Haley, Jesse Allen, and Liz Allan President Biden issued an executive order on the “Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence.” It says entities need to report large-scale computing clusters and the total computing power available, including “any model that was trained using a quantity of computing power greater than 1,026 inte... » read more

Blog Review: November 1


Cadence’s Rich Chang finds that although UVM has being used for testbench creation for more than a decade, it is still challenging to debug problems that are inside of UVM testbench. Siemens’ Keith Felton suggests that early analysis in complex advanced packaging flows can enable designers to spot potential issues early to avoid built-in constructs that cause design failures and require ... » read more

What Will That Chip Cost?


In the past, analysts, consultants, and many other experts attempted to estimate the cost of a new chip implemented in the latest process technology. They concluded that by the 3nm node, only a few companies would be able to afford them — and by the time they got into the angstrom range, probably nobody would. Much has changed over the past few process nodes. Increasing numbers of startups... » read more
