Analog Design Complicates Voltage Droop


Experts at the Table: Semiconductor Engineering sat down to talk about voltage droop in analog and mixed-signal designs, and the need for multi-vendor tool interoperability and more precision, with Bill Mullen, distinguished engineer at Ansys; Rajat Chaudhry, product management group director at Cadence; Heidi Barnes, senior applications engineer at Keysight; Venkatesh Santhanagopalan, product ... » read more

Using Real Workloads To Assess Thermal Impacts


Thermal analysis is being driven much further left in the design, fueled by demand for increased transistor density and more features on a chip or in a package, as well as the unique ways the various components may be exercised or stressed. However, getting a clear picture of the thermal activity in advanced-node chips and packages is extremely complex, and it can vary significantly by use c... » read more

Data Formats For Inference On The Edge


AI/ML training traditionally has been performed using floating point data formats, primarily because that is what was available. But this usually isn't a viable option for inference on the edge, where more compact data formats are needed to reduce area and power. Compact data formats use less space, which is important in edge devices, but the bigger concern is the power needed to move around... » read more

Next-Gen Power Integrity Challenges


Experts at the Table: Semiconductor Engineering sat down to discuss power integrity challenges and best practices in designs at 7nm and below, and in 2.5D and 3D-IC packages, with Chip Stratakos, partner, physical design at Microsoft; Mohit Jain, principal engineer at Qualcomm; Thomas Quan, director at TSMC; and Murat Becer, vice president at Ansys. What follows are excerpts of that conversatio... » read more

The Uncertain Future Of In-Memory Compute

What follows are excerpts of that conversation. Part one of this conversation can be found here and part 3 is h... » read more

Flipping Processor Design On Its Head


AI is changing processor design in fundamental ways, combining customized processing elements for specific AI workloads with more traditional processors for other tasks. But the tradeoffs are increasingly confusing, complex, and challenging to manage. For example, workloads can change faster than the time it takes to churn out customized designs. In addition, the AI-specific processes may ex... » read more

An Entangled Heterarchy


For decades, a form of structural hierarchy has been the principal means of handling complexity in chip design. It's not always perfect, and there is no ideal way in which to divide and conquer because that would need to focus on the analysis being performed. In fact, most systems can be viewed from a variety of different hierarchies, equally correct, and together forming a heterarchy. The e... » read more

SRAM In AI: The Future Of Memory


Experts at the Table — Part 1: Semiconductor Engineering sat down to talk about AI and the latest issues in SRAM with Tony Chan Carusone, CTO at Alphawave Semi; Steve Roddy, chief marketing officer at Quadric; and Jongsin Yun, memory technologist at Siemens EDA. What follows are excerpts of that conversation. Part two of this conversation can be found here and part three is here. [L-R]: ... » read more

Startup Funding: October 2023


Investors are betting heavily on data center technology, with October funding going to companies developing data processing units (DPUs) to accelerate a variety of tasks, a near-memory distributed dataflow architecture for AI, and liquid cooling technology. Much of this is linked to the build-out of the edge, closer to the source of the data than the cloud but not as compute-intensive. Other ... » read more

RISC-V Wants All Your Cores


RISC-V is no longer content to disrupt the CPU industry. It is waging war against every type of processor integrated into an SoC or advanced package, an ambitious plan that will face stiff competition from entrenched players with deep-pocketed R&D operations and their well-constructed ecosystems. When Calista Redmond, CEO for RISC-V International, said at last year's summit that RISC-V w... » read more
