Accelerating Analog Design Migration


Today’s electronic chips are commonly comprised of a mix of analog, RF, and digital components, with increasing functionalities, complexities, and numbers of transistors reaching the trillions. While the digital side of the house can take advantage of automated design implementation tools, the analog world has always been more about doing things manually and in a very “custom” way—which... » read more

Network-on-Chips Enabling Artificial Intelligence/Machine Learning Everywhere


Recently, I attended the AI HW Summit in Santa Clara and Autosens in Brussels. Artificial intelligence and machine learning (AI/ML) were critical themes for both events, albeit from different angles. While AI/ML as a buzzword is very popular these days in all its good and bad ways, in discussions with customers and prospects, it became clear that we need to be precise in defining what type of A... » read more

Formal Verification Best Practices: Investigating A Deadlock


To ensure a design is deadlock free with formal verification, one approach consists in verifying that it is “always eventually” able to respond to a request. The wording is important. Regardless of the current state and the number of cycles we must wait, in the future the design must respond. This translates very nicely using a type of SystemVerilog Assertion called “liveness propertie... » read more

IBM’s Energy-Efficient NorthPole AI Unit


At this point it is well known that from an energy efficiency standpoint, the biggest bang for the back is to be found at the highest levels of abstraction. Fitting the right architecture to the task at hand i.e., an application specific architecture, will lead to benefits that are hard or impossible to claw back later in the design and implementation flow.  With the huge increase in the inter... » read more

Thoughts On AI Consciousness


By Anda Ioana Enescu Buyruk and Catalin Tudor The rapid advancement of artificial intelligence (AI) has sparked profound discussions regarding the possibility of AI systems achieving consciousness. Such a development carries immense implications, forcing us to redirect our focus from studying the behavior of other organisms to scrutinizing ourselves. This article will delve into the concept ... » read more

Use Tcl To Save Signals More Efficiently In AMS Simulations


Saving signal waveforms during a simulation is one of the basic ways to check the simulation results. However, with large SoC designs, it’s not always practical to save all signals during simulation, and the simulation performance might also be impacted by the number of signals being saved. Therefore, a crucial part of the simulation setup is to specify the expected and essential signals to s... » read more

A Shift Left Strategy Is One Part Of A Holistic Approach To IC Design Verification


The whole is more than the sum of its parts. –Aristotle A machine is nothing more than a collection of nuts, bolts, wheels, gears, wires, pipes, chains, and what have you. And yet, when they are all connected up properly, magic happens. Instead of a pile of parts, you have a car, or a dishwasher, or a nuclear reactor. The connections and interactions between all those parts turns the whole... » read more

High-Quality Silicon With Cloud-Based Verification


New materials, vertically stacked architectures, and angstrom-level process technologies—the complexity of today’s SoCs continues to grow to meet the needs of demanding applications such as AI, autonomous vehicles, and high-performance computing. This trend only places greater pressure on verification, already notorious for being a significant bottleneck in chip development. Design teams... » read more

Performance & Efficiency Cores For Servers


HotChips 2023 was held August 27-29, 2023 at Stanford University in California and was the first in-person version of the conference in 4 years. The conference was held in a hybrid format that had over 500 participants in-person and over 1,000 attending virtually online. Topics covered a broad range of advancements in computing, connectivity, and computer architecture. Both AMD and Intel gav... » read more

Balancing IR Drop Unpredictability With Post-Silicon Flexibility


The concept of IR drop in silicon chips has always been a crucial aspect of chip design. However, recent technological trends and the emergence of new challenges, such as voltage-sensitive paths, have introduced a degree of uncertainty in predicting and effectively managing IR drop. These uncertainties are driving the need for a more flexible approach in mitigating on-die voltage droop. Increa... » read more
