Using Machine Learning To Automate Debug Of Simulation Regression Results
By Synopsys - 08 Feb, 2023 - Comments: 0

Regression failure debug is usually a manual process wherein verification engineers debug hundreds, if not thousands of failing tests. Machine learning (ML) technologies have enabled an automated debug process that not only accelerates debug but also eliminates errors introduced by manual efforts. This white paper discusses how verification engineers can more efficiently analyze, bin, triage... » read more

A New Year’s Wish
By Brian Bailey - 26 Jan, 2023 - Comments: 0

Every year I run a predictions article. It is a mashup of ideas from many people within the industry, and while many predictions are somewhat self-serving, there are other which come more from the heart — or perhaps they are dreams rather than expectations. I see hope in some of those, particularly the ones that look toward sustainability within our industry, and of our industry. Just like... » read more

Power Issues Causing More Respins At 7nm And Below
By Brian Bailey - 26 Jan, 2023 - Comments: 0

Power consumption has been a major design consideration for some time, but it is far from being a solved issue. In fact, an increasing number of designs have a plethora of power-related problems, and those problems are getting worse in new chip designs. Many designs today are power-limited — or perhaps more accurately stated, thermal-limited. A chip only can consume as much power as it is ... » read more

EDA, IP Growth Surges Again
By Ed Sperling - 24 Jan, 2023 - Comments: 0

EDA tools and IP revenue increased 8.9% in Q3 of 2022 to $3.767 billion, up from $3.458 billion in 2021, according to a just-released report from the ESD Alliance at SEMI. All regions except Japan reported growth, but the numbers were a bit more uneven in Q3 than in recent quarters. For example, total silicon IP dropped 1%, while services revenue grew 20.8%. At the same time, EDA revenue jum... » read more

Selecting The Right RISC-V Core
By Brian Bailey - 16 Jan, 2023 - Comments: 0

With an increasing number of companies interested in devices based on the RISC-V ISA, and a growing number of cores, accelerators, and infrastructure components being made available, either commercially or in open-source form, end users face an increasingly difficult challenge of ensuring they make the best choices. Each user likely will have a set of needs and concerns that almost equals th... » read more

Design And Verification Methodologies Breaking Down
By Brian Bailey - 12 Jan, 2023 - Comments: 0

Tools, methodologies and flows that have been in place since the dawn of semiconductor design are breaking down, but this time there isn't a large pool of researchers coming up with potential solutions. The industry is on its own to formulate those ideas, and that will take a lot of cooperation between EDA companies, fabs, and designers, which has not been their strong point in the past. It ... » read more

Hardware Trojan Detection Case Study Based on 4 Different ICs Manufactured in Progressively Smaller CMOS Process Technologies
By Technical Paper Link - 11 Jan, 2023 - Comments: 0

A technical paper titled "Red Team vs. Blue Team: A Real-World Hardware Trojan Detection Case Study Across Four Modern CMOS Technology Generations" was published by researchers at Max Planck Institute for Security and Privacy, Université catholique de Louvain (Belgium), Ruhr University Bochum, and Bundeskriminalamt. "In this work, we aim to improve upon this state of the art by presenting a... » read more

Reducing Simulation Regression Turnaround Time With Dynamic Performance Optimization
By Synopsys - 10 Jan, 2023 - Comments: 0

No single step in the development of semiconductor devices is more sensitive to speed than functional simulation. A modern system-on-chip (SoC) design simulates billions of cycles of operation in the process of completing the verification plan and achieving coverage goals. To validate full system functionality, many of these simulations include running code on one or more embedded processors. E... » read more

How Secure Are RISC-V Chips?
By Jeff Goldman - 05 Jan, 2023 - Comments: 3

When the Meltdown and Spectre vulnerabilities were first uncovered in 2018, they heralded an industry-wide shift in perspective regarding processor security. As the IBM X-Force Threat Intelligence Index put it the following year, "2018 ushered in a new era of hardware security challenges that forced enterprises and the security community to rethink the way they approach hardware security." R... » read more

Hardware Fuzzing (U. of Michigan, Google, Virginia Tech)
By Technical Paper Link - 18 Dec, 2022 - Comments: 0

A technical paper titled "Fuzzing Hardware Like Software" was published by researchers at University of Michigan, Google and Virginia Tech. The paper was presented at the 2022 Usenix Security Symposium. Abstract: "Hardware flaws are permanent and potent: hardware cannot be patched once fabricated, and any flaws may undermine even formally verified software executing on top. Consequently, ve... » read more
