Last week at the RISC-V Summit in Santa Clara, NVIDIA’s Vice President of Multimedia Architecture/ASIC, Frans Sijstermans, took to the stage to recount NVIDIA’s strategic transformation. For an audience of engineers, developers, and industry insiders, Sijstermans’ keynote was both an inside look at NVIDIA’s journey with RISC-V and a demonstration of how open architecture has fueled rapid technological growth. Over the past seven years, NVIDIA’s adoption of RISC-V has marked a major shift in its approach to microprocessor design, from the niche Falcon core to a globally scaled RISC-V integration that now spans billions of cores.
From Falcon to RISC-V: A Strategic LeapIn 2017, Sijstermans first announced NVIDIA’s plan to phase out Falcon, their proprietary 32-bit microprocessor, and adopt RISC-V. At the time, Falcon had been used for a decade, embedded across various applications. But as computing demands grew more complex, NVIDIA recognized the need for a more adaptable, extensible architecture. After evaluating multiple architectures, the company found RISC-V’s open, customizable foundation aligned with its goals for scalability, security, and performance. “Customization is really the key here,” Sijstermans emphasized. “As Moore’s Law slows, it becomes increasingly important to use every bit of silicon effectively. RISC-V’s customizable structure allows us to design specific extensions for our applications.” This customization became one of RISC-V’s most appealing attributes for NVIDIA, which has since been able to innovate rapidly within the flexible framework the architecture provides.

Unlike traditional integrated circuit (IC) designs, multi-dimensional 2.5D and 3D ICs are composed of multiple individual chiplets, each built to a separate process node best suited for its specific purpose. There are many different design options for connecting these chiplets, and any or all of these approaches can be combined on a single 3D IC assembly. This results in multiple components of different materials integrated in all three dimensions, which creates new and unique verification challenges for 2.5/3D IC designers. 3D IC assembly flow Multi-dimensional ICs are one part of the industry’s answer to moving beyond the limits of Moore’s law. While 2.5D approaches, particularly chiplets placed upon a silicon interposer, have gained broad adoption, the move to true 3D IC is still early in its design lifecycle. Design tools and best design practices continue to evolve and improve, but many challenges are yet to be resolved. In a true 3D IC, early design and package planning can be a challenging task, as the specific approach, materials, and chiplet placements used will induce thermal and mechanical stresses that can impact the intended electrical behavior of the full assembly design (Figure 1). Selecting the optimal approach and optimal chiplet placements becomes critical, implying multiple iterations will be required to determine the best final design.  Figure 1. Packaged 3D IC with non-uniform power distribution.

 David Abercrombie By David AbercrombieIn motor car racing, many people think the win happens on the track, with lightning-fast pit stops ensuring the fastest car takes the black and white checkered flag at the finish line. In reality, the win happened long ago, in the garage, as the car was built and tested and rebuilt. The same is true in integrated circuit (IC) design. Getting a design through a successful tapeout on schedule isn’t just the result of signoff verification. It begins much earlier, back in the design and implementation stages. Finding and correcting critical errors in these early design stages helps design teams make adjustments quickly while layouts are still more open and flexible, avoiding time-consuming and complex fixes during signoff that can play havoc with delivery schedules. But what happens when that early verification doesn’t match signoff verification? Despite all the work designers put in during the design stages, they may find themselves still trying to fix those hard errors, only now they’re constrained by layout restrictions, and under the gun to meet the schedule. Calibre® shift left (early design-stage) solutions bring industry-leading Calibre signoff-quality verification and design optimization into the design and implementation environments. Shift left verification and optimization can help design teams minimize those late-stage signoff iterations while still delivering high performance, high reliability designs. Using the same qualified rule decks and underlying engines used by the signoff toolsuite, Calibre shift left tools and technology deliver targeted verification that hones in on those errors most critical in early-stage designs, provide thorough analysis of complex design constraints, support designers with guided debugging to enable optimal fixes that remain signoff-compliant throughout the design flow, and apply selective automated design optimizations, all within a user-friendly toolset integrated into the designer’s design or implementation environment.

By David Abercrombie and Michael White No matter what process node you’re working at, or how big or how complex your integrated circuit (IC) design is, design enablement is a complex process that goes through multiple stages. The faster you get your design to market, the better your chances of achieving your market goals. But getting your design to the foundry on schedule, while ensuring the final product will not only be manufacturable, but also provide the intended performance and reliability, all depends on achieving and maintaining high productivity and quality of results throughout the design flow.
IC design companies, like any other business, constantly look for ways to improve and speed up their processes. One approach that has recently gained significant traction is the idea of “shifting left”—performing design layout verification and optimization earlier in the design flow, instead of waiting until the signoff verification stage. However, simply shifting signoff physical verification to earlier stages of the design flow is neither practical nor productive. Signoff verification is intended to apply to full chip designs where all components are complete and connected. Running signoff verification on incomplete or “dirty” designs is not only time-consuming, but also returns millions of errors, many of which are irrelevant, as they are caused by the incomplete nature of the layout. Hardly the increase in productivity the design companies were hoping for.

By: Abu Sebastian, Manuel Le Gallo-Bourdeau, Vijay Narayanan The energy-efficient chip showcases critical building blocks of a scalable mixed-signal architecture. A rendering of IBM’s analog AI chip. We’re just at the beginning of an AI revolution that will redefine how we live and work. In particular, deep neural networks (DNNs) have revolutionized the field of AI and are increasingly gaining prominence with the advent of foundation models and generative AI. But running these models on traditional digital computing architectures limits their achievable performance and energy efficiency. There has been progress in developing hardware specifically for AI inference, but many of these architectures physically split the memory and processing units. This means the AI models are typically stored in a discrete memory location, and computational tasks require constantly shuffling data between the memory and processing units. This process slows down computation and limits the maximum achievable energy efficiency. EDACafe Industry Predictions for 2023 – ThaliaFebruary 1st, 2023 by Sanjay Gangal
By Sowmyan Rajagopalan, CEO, Thalia Design Automation Sowmyan Rajagopalan The economic outlook for semiconductor industry in 2023 Since the start of the Covid-19 pandemic in 2020, the global market for semiconductors has not looked very stable. It has made long-term planning tough if not impossible. A forecast fall then turned into a rapid growth, followed by an oversupply problem with excess inventories. In 2021, more than $0.5 trillion units were shipped, which was a record, and represented a significant 26.2% growth in value over 2020. That growth continued into 2022, with semiconductor industry growing at 7.3%. So what’s coming further down the track? Due to an oversupply issue and slower demand in consumer electronics, Gartner’s forecast for 2023 is a small decline in the market by 2.5%. Even with that modest decline, we are still looking at a staggering $620 billion semiconductor market this year. However, the market for automotive electronics continues to evolve to support the rapidly increasing volume of devices in the modern vehicle: from non-critical systems in audio, video, satellite navigation and connectivity devices, to fundamental systems in battery control, and mission critical Advanced Driver Assistance Systems (ADAS) and monitoring systems. Although analysts’ numbers differ, the forecasts for the growth of automotive electronics all show a similar and definite upward trajectory. The automotive industry could be a driving force for the industry – potentially leading the direction of consumer electronics with the largest tier one companies sourcing directly from foundries: changing the power balance and upsetting the decades-old structure of a tiered supply chain in automotive manufacturing.

By Kella Knack, Senior Director of Strategic Marketing, Avishtech Kella Knack 2023: The Year of Refining the Role of EDA Toolsets One year ago, as an industry as well as a country and world, we were dealing with the remnants of COVID-19 and its resultant effects on business. Those efforts centered on a variety of global issues—fabrication facilities having limited manufacturing staffs and production capabilities; “rolling” shut downs of various facilities; materials shortages; shipping capabilities and cost, and most impactful, the global chip shortage. The “Sort of” Cloudy Crystal Ball for ‘23 As we move towards the end of 2022 and the beginning of 2023, we are still challenged by on-going global chip shortages. And, there are also two more significant wrinkles:
There are some silver linings resulting from the foregoing: new defense contracts the likes of which we have not seen in a long time and U.S.-based chip manufacturing operations that will help to address the global chip shortage and relieve our strong dependency on Taiwanese manufacturing operations.
