Missing Interposer Abstractions And Standards
By Brian Bailey - 29 Nov, 2021 - Comments: 0

The design and analysis of an SoC based on an interposer is not for the faint of heart today, but the industry is aware of the challenges and is attempting to solve them. Until that happens, however, it will be a technique that only large companies can deploy because they need to treat everything almost as if it were a single die. The construction of large systems uses techniques, such as ab... » read more

Blog Review: Nov. 24
By Jesse Allen - 24 Nov, 2021 - Comments: 0

Cadence's Paul McLellan introduces the theory and practice of datapath formal verification and explores two use cases of dot-product accumulate systolic design and hashing design. Siemens EDA's Rich Edelman shows that constructing an in-order UVM scoreboard doesn't have to be a difficult or complex task, and certainly simpler than replacing a laptop's keyboard. Synopsys' Gordon Cooper con... » read more

Product Lifecycle Management For Semiconductors
By Brian Bailey - 23 Nov, 2021 - Comments: 1

Product lifecycle management (PLM) and the semiconductor industry have always been separate, but pressure is growing to integrate them. Automotive, IIoT, medical, and other industries see that as the only way to manage many aspects of their business, and as it stands, semiconductors are a large black box in that methodology. The technology space is driven by a mix of top down and bottom-up p... » read more

Advanced Packaging Shifts Design Focus To System Level
By Ann Mutschler - 23 Nov, 2021 - Comments: 0

Growing momentum for advanced packaging is shifting design from a die-centric focus toward integrated systems with multiple die, but it's also straining some EDA tools and methodologies and creating gaps in areas where none existed. These changes are causing churn in unexpected areas. For some chip companies, this has resulted in a slowdown in hiring of ASIC designers and an uptick in new jo... » read more

Gaps In The AI Debug Process
By Brian Bailey - 23 Nov, 2021 - Comments: 0

When an AI algorithm is deployed in the field and gives an unexpected result, it's often not clear whether that result is correct. So what happened? Was it wrong? And if so, what caused the error? These are often not simple questions to answer. Moreover, as with all verification problems, the only way to get to the root cause is to break the problem down into manageable pieces. The semico... » read more

Improving Predictability Through Design Solutions Methodologies
By Rusty Stuber - 23 Nov, 2021 - Comments: 0

“Plans are useless, but planning is indispensable.” – Dwight D. Eisenhower Our first article called for the need to change how we think about verification. In this follow-up, we dive deeper into the tools needed for today’s verification. Project milestones are destined to move. Development estimates are rough and almost always optimistic. Each development stage contains interdepe... » read more

Batch Filters: A Better, Faster Way To Filter Large DRC Results Databases
By Siemens EDA - 22 Nov, 2021 - Comments: 0

Reviewing massive DRC results databases (RDBs) can be a time-consuming stage in traditional debug flows, due primarily to the loading, filtering, and display times associated with these large datasets. Finding the most effective approach to filtering results data is important to optimize both results debug time and resource usage. While smaller databases that load quickly in GUI applications ca... » read more

Week In Review: Design, Low Power
By Jesse Allen - 19 Nov, 2021 - Comments: 0

Tools Imperas Software released updated simulator and reference models that support the latest RISC-V extensions for Bit Manipulation 1.0.0, Cryptographic (Scalar) 1.0.0, and Vector 1.0, plus Privilege Specification 1.12. They are offered both as freely available, open-source reference models for the RISC-V community as well as commercial products. Ansys' multiphysics signoff solutions were... » read more

Zonal Architectures Play Key Role In Vehicle Security
By Ann Mutschler - 17 Nov, 2021 - Comments: 1

The automotive ecosystem is starting to shift toward zonal architectures, making vehicle functionality less dependent on the underlying hardware and allowing more flexibility in what gets processed where. The impact of that shift is both broad and significant. For carmakers, it could lead to hardware consolidation and more options for failovers in case something goes wrong with any system in... » read more

Blog Review: Nov. 17
By Jesse Allen - 17 Nov, 2021 - Comments: 0

In a podcast, Arm's Geof Wheelwright and Hilary Tam chat about the importance of efforts to decarbonize compute and how low-power compute can help ensure that the benefits of technology outweigh the environmental cost. Synopsys' Graham Allan and Vikas Gautam consider what's driving demand for HBM3, what's different from the previous HBM2E specification, unique design considerations, and how ... » read more
