RISC-V Micro-Architectural Verification


RISC-V processors are garnering a lot of attention due to their flexibility and extensibility, but without an efficient and effective verification strategy, buggy implementations may lead to industry problems. Prior to RISC-V, processor verification almost became a lost art for most semiconductor companies. Expertise was condensed into the few commercial companies that provided processors or... » read more

What You Needed To Know In 2023


I always use the last blog of the year to review everything published in the Systems & Design and Low Power – High Performance channels of Semiconductor Engineering, the two channels that I write for. It is useful to see what interests you and, as I have found in the past, it is an indicator of where the industry is going. You read about the issues you are facing as designers, and you nee... » read more

Dramatic Changes Ahead For Chips And Systems


Early this year, most people had never heard of generative AI. Now the entire world is racing to capitalize on it, and that's just the beginning. New markets, such as spatial computing, quantum computing, 6G, smart infrastructure, sustainability, and many more are accelerating the need to process more data faster, more efficiently, and with much more domain specificity. Compared to the days ... » read more

2023: A Good Year For Semiconductors


Looking back, 2023 has had more than its fair share of surprises, but who were the winners and losers? The good news is that by the end of the year, almost everyone was happy. That is not how we exited 2022, where there was overcapacity, inventories had built up in many parts of the industry, and few sectors — apart from data centers — were seeing much growth. The supposed new leaders we... » read more

Balancing Memory And Coherence: Navigating Modern Chip Architectures


In the intricate world of modern chip architectures, the "memory wall" – the limitations posed by external DRAM accesses on performance and power consumption growing slower than the ability to compute data – has emerged as a pivotal challenge. Architects must strike a delicate balance between leveraging local data reuse and managing external memory accesses. While caches are critical for op... » read more

Shedding More Light On Photonics For Multi-Die Systems


By Kenneth Larsen and Twan Korthorst Photonics harness the speed of light for fast, low-power, high-capacity data transfer. A tremendous amount of data needs to be moved swiftly across different components in a multi-die system. Considering this, exploiting the advantages of light is one way to mitigate heat dissipation and energy consumption concerns while delivering fast data transmission.... » read more

Extending DTCO For Today’s Competitive IC Landscape


As semiconductor components continue to shrink, the challenges associated with design-for-manufacturing (DFM) and design-technology co-optimization (DTCO) increase. The complexity of the IC design and manufacturing process demands an extension of traditional DFM and DTCO techniques to overcome the systematic failures tied to complex design-process interactions. Designers need to accelerate d... » read more

Unraveling PCIe 6.0 Loopback And Digital Near-End Loopback Feature


The PCIe specification has given a specific Link Training and Status State Machine (LTSSM) state named Loopback, which is intended for test and fault isolation use. Basically, it gives a mechanism that involves looping back the data that was received in the Loopback LTSSM state. The entry and exit behavior are specified, and all other details are implementation-specific. Loopback can op... » read more

Field Testing In 5G NR


5G NR network coverage measurements will be beam-based instead of cell-based. This will change the methodology of coverage KPI calculation. The amount of reference signals in the air is increasing as there will be multiple reference beams per cell, posing more stringent performance requirements for scanning receivers and test UEs. Both test UEs and scanners will be needed for 5G NR field verifi... » read more

Shattered Silos: 2024’s Top Technology Trends


Technological innovation is increasingly focused on solving pressing, global challenges like climate change, disaster response, and accessible, preventative healthcare. Time is of the essence in finding solutions to these issues. On the global stage, the deadline for the United Nations (UN) 2030 Agenda for Sustainable Development, a framework of strategies to tackle climate change, improve heal... » read more
