Blog Review: Sept. 25


Cadence’s Mamta Rana digs into how PCIe 6.1 ECN builds on the FLIT-based architecture introduced in PCIe 6.0, further optimizing flow control mechanisms to handle increased data rates and improved efficiency but making verification of shared credit updates essential. Siemens’ Nicolae Tusinschi provides a primer on formal verification, including what makes it different from simulation, pr... » read more

How Die Dimensions Challenge Assembly Processes


Multi-die assemblies are becoming more common and more complex due to technology advancements and market demands, but differing die dimensions are making this process increasingly challenging. To fully enable a multi-chiplet ecosystem, standardized component handling and interfaces are needed. The underlying concept is similar to LEGO blocks that simply snap together, yet it's nowhere near t... » read more

Blog Review: Sept. 18


Siemens’ Kyle Fraunfelter explores the similarities between hurricane forecasting and semiconductor manufacturing to argue for the value of integrating real-time wafer fabrication measurements into the digital twin models used to simulate the semiconductor fabrication process. Cadence’s Rohini Kollipara introduces Display Stream Compression (DSC), which can enable higher resolutions and ... » read more

Is PPA Relevant Today?


The optimization of power, performance, and area (PPA) has been at the core of chip design since the dawn of EDA, but these metrics are becoming less valuable without the context of how and where these chips will be used. Unlike in the past, however, that context now comes from factors outside of hardware development. And while PPA still serves as a useful proxy for many parts of the hardwar... » read more

Higher Density, More Data Create New Bottlenecks In AI Chips


Data movement is becoming a bigger problem at advanced nodes and in advanced packaging due to denser circuitry, more physical effects that can affect the integrity of signals or the devices themselves, and a significant increase in data from AI and machine learning. Just shrinking features in a design is no longer sufficient, given the scaling mismatch between SRAM-based L1 cache and digital... » read more

Understanding The Total Cost Of Ownership In HPC And AI Systems


Cost is often the deciding factor when it comes to purchasing decisions at an organization, particularly those dealing with high-tech investments. When organizations evaluate proposals for new procurements, the initial capital cost of the system often receives significant attention. A great deal of preparation and planning goes into the decision to make a large purchase. While this is a critica... » read more

The Challenges Of Upgrading Lithium Batteries


The ongoing electrification of everyday items has resulted in the proliferation of batteries, and spurred continued development for automotive and grid use. Lithium-ion batteries still dominate the rechargeable-battery landscape, with solid-state versions prolonging that position, but other lithium variants aim for greater safety while raising energy capacity. Battery researchers must balanc... » read more

Blog Review: Sept. 11


Cadence's Neha Joshi introduces the IEEE 1801 standard, also known as UPF (Unified Power Format), which offers a uniform framework for defining power domains, power states, and power intent to ensure consistency across diverse tools and phases of the design process. Siemens' John McMillan warns that known good die may not behave the same in 3D-ICs as they do standalone and suggests that mult... » read more

Challenges and Best Practices for TCO Models of Technical Computing Resources for Engineering Modeling and Simulation Workflows


Many organizations focus heavily on the system’s initial capital cost when developing criteria and reviewing proposals for new procurements. While this is crucial for evaluating ROI, research shows that the initial purchase cost accounts for only half of the total expenses over the system’s useful life. This data point highlights the importance of understanding the total cost of ownership (... » read more

Balancing Programmability And Performance In Cars


The rate of change in the automotive industry is accelerating with the shift toward software-defined vehicles and ongoing advancements in algorithms and chip architectures. The challenge now is to figure out the best way to prevent rapid obsolescence, improve safety, and keep the cost of these changes to a minimum. Today, updatable automotive hardware is typically achieved through FPGAs, but... » read more
