Multiple Challenges Emerge With Physical AI System Design


Physical AI holds the promise of making everything from robots to a slew of mobile edge devices much more interactive and useful, but it will significantly alter how systems are designed, verified, and monitored. Physical AI systems need to work both independently and together. They need the ability to make decisions quickly and locally, typically using much less power than other types of AI... » read more

Blog Review: Oct. 22


Cadence's Sandip Sadadiya shows what's new in the AMBA AXI Issue L protocol update, which introduces a new credit-based transport mechanism that replaces the traditional VALID/READY handshake, along with improved flow control mechanisms. Siemens' Farhad Ahmed highlights the growing need to do clock domain crossing (CDC) and reset domain crossing (RDC) analysis in a hierarchical way and intro... » read more

Chip Industry Week in Review


The Open Compute Project (OCP) Summit kicked off this week in San Jose, dominated by open standards, massive scaling of AI infrastructure, chiplet architectures, and energy-efficiency. Among the highlights: An initiative to standardize data center infrastructure and advance Ethernet for AI. New contributions to OCP's Open Chiplet Economy ecosystem, including Arm's new Foundation Chiplet... » read more

Achieving Reliable 2m+ DAC Connectivity For AI Scale Networks With 224G PHY IP


As artificial intelligence workloads and hyperscale data centers continue to evolve, the requirements for networking infrastructure are becoming increasingly stringent. High-speed, reliable connectivity is essential to support the massive data flow and low-latency demands of AI-scale environments. Passive direct attach copper (DACs) remains an attractive choice for hyperscalers and system vendo... » read more

Data Centers Boost Voltage For Higher Efficiency


The power architecture used in HPC and AI data centers today is about to undergo a significant change in an effort to boost power efficiency. While voltages at the chip level will remain the same, the voltages leading to those chips will be kept higher for longer distances. This change has broad implications for DC-DC converters. The existing architecture brings AC to each rack, converts it ... » read more

Startup Tips To Get From Seed Funding To Series A, B, C


Startups are often created by experienced engineers who figure out how to solve a technical problem they are dealing with at work, or by PhD candidates in research labs before they have even started their first full-time job. Either way, getting seed money to the tune of a few million dollars is relatively easy compared to securing further rounds of funding and achieving the company’s exit go... » read more

Developing Next-Generation Integrated Optical Engines


By Susan Coleman and Emily Gerken Data demand is soaring worldwide as high-resolution video streaming, virtual reality, the Internet of Things (IoT), high-performance computing (HPC), and artificial intelligence and machine learning (AI/ML) drive an insatiable appetite for data. As a result, networks and data centers face increasing pressure to expand bandwidth, reduce latency, and lower pow... » read more

Current Problems Grow For Power Delivery


IR drop is becoming more problematic for a growing proportion of designs, an indication that the power delivery network (PDN) is not providing enough current to parts of the design when required. Unfortunately, there is no easy fix to this problem. In the past, when voltages were much higher, a small voltage droop didn't really matter. At the same time, wires were much thicker and presented ... » read more

Optimizing Optical Fiber Connections In Hyperscale Datacenters: A Simulation-Driven Approach


Hyperscale datacenters are redefining the limits of data transmission technology, driven by increasing demands for higher bandwidth, lower power consumption, and reduced latency. Through advanced simulation workflows and multiphysics integration, engineers can design, optimize, and validate optical coupling systems for next-generation datacenters. The use of Ansys Optics software for photonic c... » read more

Enabling The 448G Era: System Architecture And Standards For Next-Gen AI Networks


As Artificial Intelligence (AI) and Machine Learning (ML) workloads continue to reshape data center infrastructure, the need for higher bandwidth and lower latency has accelerated the need for a next-generation Ethernet. This white paper examines the industry’s shift toward 448G signaling—driven by scale-up and scale-out AI cluster demands—and outlines the evolving system architecture... » read more
