How The Doubling Of Interconnect Bandwidth With PCI Express 6.0 Impacts IP Electrical Validation
By Synopsys - 09 May, 2023 - Comments: 0

As a result of the innovations taking place in CPUs, GPUs, accelerators, and switches, the interface in hyperscale datacenters now requires faster data transfers both between compute and memory and onto the network. PCI Express (PCIe) provides the backbone for these interconnects and is used to build protocols such as Computer Express Link (CXL) and Universal Chiplet Interconnect Express (UCIe... » read more

Challenges In Writing SDC Constraints
By Ed Sperling - 08 May, 2023 - Comments: 0

Writing design constraints is becoming more difficult as chips become more heterogeneous, and as they are expected to function longer in the field. Timing and power can change over time, and constraints need to be adjusted to that changing context. Synopsys’ Ajay Daga, group director for R&D at Synopsys, talks about the challenges in pushing constraints down to different hierarchical portions... » read more

Week In Review: Semiconductor Manufacturing, Test
By Gregory Haley - 05 May, 2023 - Comments: 0

The global sales slump in semiconductors but may be stabilizing, according to a new report from the Semiconductor Industry Association (SIA). Worldwide sales of semiconductors fell 8.7% in Q1 2023 compared to the Q4 2022, and dropped 21.3% compared to the Q1 2022. Sales for the month of March 2023 increased 0.3% compared to February 2023. Meanwhile, SEMI reports worldwide silicon wafer shipment... » read more

ML Automotive Chip Design Takes Off
By Ann Mutschler - 04 May, 2023 - Comments: 0

Machine learning is increasingly being deployed across a wide swath of chips and electronics in automobiles, both for improving reliability of standard parts and for the creation of extremely complex AI chips used in increasingly autonomous applications. On the design side, the majority of EDA tools today rely on reinforcement learning, a machine learning subset of AI that teaches a machine ... » read more

Going Virtual In Automotive Electronics Development
By Filip Thoen - 04 May, 2023 - Comments: 0

Developing the electrical/electronic (E/E) systems in automobiles and other vehicles has always been challenging due to the rough environmental conditions experienced on the road and the high expectations for safety and reliability. In recent years, these challenges have been exacerbated by several industry trends. They have triggered a revolution in how electronic control units (ECUs) are desi... » read more

Data Leakage Becoming Bigger Issue For Chipmakers
By Ed Sperling - 04 May, 2023 - Comments: 0

Data leakage is becoming more difficult to stop or even trace as chips become increasingly complex and heterogeneous, and as more data is stored and utilized by chipmakers for other designs. Unlike a cyberattack, which typically is done for a specific purpose, such as collecting private data or holding a system ransom, data leaks can spring up anywhere. And as the value of data increases, th... » read more

Role Of IoT Software Expanding
By John Koon - 04 May, 2023 - Comments: 0

IoT software is becoming much more sophisticated and complex as vendors seek to optimize it for specific applications, and far more essential for vendors looking to deliver devices on-time and on-budget across multiple market segments. That complexity varies widely across the IoT. For example, the sensor monitoring for a simple sprinkler system is far different than the preventive maintenanc... » read more

Blog Review: May 3
By Jesse Allen - 03 May, 2023 - Comments: 0

Synopsys' Thomas Andersen considers the requirements of AI-optimized chips that are resulting in exploration of different memory configurations, different types of memory, and different types of processor technologies and software components. Cadence's Girish Vaidyanathan considers the role of hierarchy and partitioning in custom design and looks at how a virtual hierarchy allows layout desi... » read more

Accelerating Coverage Closure With AI-Based Verification Space Optimization
By Synopsys - 03 May, 2023 - Comments: 0

Coverage is at the heart of all modern semiconductor verification. There is no maxim more fundamental to this process than “if you haven’t exercised it, you haven’t verified it.” Although covering a particular aspect of a chip design does not guarantee that all bugs are found — bug effect propagation and checker quality are also key factors — it is certainly true that bugs cannot po... » read more

AI Adoption Slow For Design Tools
By Brian Bailey - 01 May, 2023 - Comments: 0

A lot of excitement, and a fair amount of hype, surrounds what artificial intelligence (AI) can do for the EDA industry. But many challenges must be overcome before AI can start designing, verifying, and implementing chips for us. Should AI replace the algorithms in use today, or does it have a different role to play? At the end of the day, AI is a technique that has strengths and weaknesses... » read more
