From Cloud To Cloudlets


Cloudlets, or mini-clouds, are starting to roll out closer to the sources of data in an effort to reduce latency and improve overall processing performance. But as this approach gains steam, it also is creating some new challenges involving data distribution, storage and security. The growing popularity of distributed clouds is a recognition that the cloud model has limitations. Sending the ... » read more

How UVM Callbacks Simplify Assertion Validation


By Akshay Sarup and Mark Olen Assertions bring immediate benefits to the whole design and verification cycle; thus any challenges engineers face in coding and testing them are worth resolving. When a large number of assertions are to be validated, callbacks save time by eliminating the need to code a new sequence for each scenario. Callbacks also provide more dynamic and fine-grained cont... » read more

Preparing For A Barrage Of Physical Effects


Advancements in 3D transistors and packaging continue to enable better power and performance in a given footprint, but they also require more attention to physical effects stemming from both increased density and vertical stacking. Even in planar chips developed at 3nm, it will be more difficult to build both thin and thick oxide devices, which will have an impact on everything from power to... » read more

Semiconductor Engineering sat down to discuss power optimization with Oliver King, CTO at Moortec; João Geada, chief technologist at Ansys; Dino Toffolon, senior vice president of engineering at Synopsys; Bryan Bowyer, director of engineering at Mentor, a Siemens Business; Kiran Burli, senior director of marketing for Arm's Physical Design Group; Kam Kittrell, senior product management group d... » read more

PCIe Simulation Speed-Up Using Mentor QVIP With PLDA PCIe Controller For DMA Applications


In this case study, PLDA explains how verification engineers can use Mentor’s Questa Verification IP (QVIP) to improve productivity during the functional verification of PCIe designs with DMA engines. The flexibility of Questa VIP was key to creating custom testbenches from scratch that can dynamically adapt to different IP topologies and configurations, mixing PCIe interfaces with multiple A... » read more

Chiplet Reliability Challenges Ahead


Assembling chips using LEGO-like hard IP is finally beginning to take root, more than two decades after it was first proposed, holding the promise of faster time to market with predictable results and higher yield. But as these systems of chips begin showing up in mission-critical and safety-critical applications, ensuring reliability is proving to be stubbornly difficult. The main driver fo... » read more

Blog Review: Aug. 12


Arm's Greg Yeric takes a look at what semiconductor manufacturing might look like in 2030 as the price of equipment rises and possibilities for when the next upgrade to EUV, high numerical aperture, eventually runs out of steam. Synopsys' Taylor Armerding explains the difference between bugs and security flaws and why it's so important to pay attention to potential problems in a design's spe... » read more
