Scaling AI Chip Design With NoC Soft Tiling

By Andy Nightingale - 26 Nov, 2024 - Comments: 0

Tiling is about repeating modular units within the same chip to enhance scalability and efficiency; chiplets involve combining different silicon pieces to achieve a more diverse and powerful system within a single package. Network-on-chip (NoC) soft tiling is complimentary but distinct from chiplets described above as it repeats modular units inside a NoC design. Soft tiling within a NoC off... » read more

How To Speed Up LVS Verification

By Wael elManhawy - 26 Nov, 2024 - Comments: 0

Layout versus schematic (LVS) comparison is a crucial step in integrated circuit (IC) design verification, ensuring that the physical layout of the circuit matches its schematic representation. The primary goal of LVS is to verify the correctness and functionality of the design. Traditionally, LVS comparison is performed during signoff verification, where dedicated tools compare layout and sche... » read more

Successful Design Of Power Management Chips

By Samad Parekh - 26 Nov, 2024 - Comments: 0

With an industry as large as semiconductors, there are often surprises lurking in some of the more specialized product categories. Everyone knows that huge chips such as CPUs and GPUs command high prices and that memory chips are ubiquitous. However, the domain of power management integrated circuits (PMICs) is less well known to many observers. PMICs are impressive in terms of their technol... » read more

The Latest Wireless Industry Use Cases

By Chaimaa Aarab - 26 Nov, 2024 - Comments: 0

The wireless industry evolves constantly; GSMA estimates that mobile technologies and services generated 5% of the global GDP in 2022, which equates to $5.2 trillion of economic value. In parallel, more than 5.4 billion people subscribed to a mobile service, with 4.4 billion connected to the mobile internet. These numbers are impressive, but there is much more to come. 5G networks promise exp... » read more

Outlook 2025: Embracing Chiplets

By Steve Brown - 26 Nov, 2024 - Comments: 0

The semiconductor industry is rapidly evolving, and as we look towards 2025, chiplets are at the forefront of this transformation. The shift from traditional monolithic system-on-chip (SoC) designs to chiplet-based architectures is gaining momentum, driven by the need to meet ever-increasing computing demands. This evolution is not just a trend; it represents a fundamental change in how we appr... » read more

Managing Reflections With Terminations

By John Golding - 04 Nov, 2024 - Comments: 0

Have you heard recommendations to use a particular termination in particular situations for good signal integrity? Have you ever wondered how to incorporate terminations in your design? While there are typical use cases for various terminations, sometimes engineers use termination techniques based on a recommendation or assumption that may not work, or at least may not be optimal, for their par... » read more

Reducing SoC Power With NoCs And Caches

By Andy Nightingale - 31 Oct, 2024 - Comments: 0

Today’s system-on-chip (SoC) designs face significant challenges with respect to managing and minimizing power consumption while maintaining high performance and scalability. Network-on-chip (NoC) interconnects coupled with innovative cache memories can address these competing requirements. Traditional NoCs SoCs consist of IP blocks that need to be connected. Early SoCs used bus-based archi... » read more
