What’s Missing In Test
By Anne Meixner - 19 Jun, 2024 - Comments: 0

Experts at the Table: Semiconductor Engineering sat down to discuss how functional test content is brought up at first silicon, and the balance between ATE and system-level testing, with Klaus-Dieter Hilliges, V93000 platform extension manager at Advantest Europe; Robert Cavagnaro, fellow in the Design Engineering Group at Intel (responsible for manufacturing and test strategy of data center... » read more

The Next Big Leap: Energy Optimization
By Brian Bailey - 16 Nov, 2020 - Comments: 1

The relationship between power and energy is technically simple, but its implication on the EDA flow is enormous. There are no tools or flows today that allow you to analyze, implement, and optimize a design for energy consumption, and getting to that point will require a paradigm shift within the semiconductor industry. The industry talks a lot about power, and power may have become a more ... » read more

Why Is PSS So Important?
By Ed Sperling - 25 Feb, 2020 - Comments: 0

Robert Hoogenstryd, product marketing manager at Mentor, a Siemens Business, talks about the new testbench verification language standard, what are the big advantages of using PSS, what kinds of challenges this language solves, and how much time this approach can save. » read more

Portable Stimulus And Digital Twins
By Brian Bailey - 25 Nov, 2019 - Comments: 0

It has been a year since Accellera's Portable Test and Stimulus Specification became a standard. Semiconductor Engineering sat down to discuss the impact it has had, and the future direction of it, with  Larry Melling, product management director for Cadence; Tom Fitzpatrick, strategic verification architect for Mentor, a Siemens Business; Tom Anderson, technical marketing consultant for OneSp... » read more

How To Optimize Verification
By Brian Bailey - 25 Jul, 2019 - Comments: 0

The rate of improvement in verification tools and methodologies has been nothing short of staggering, but that has created new kinds of problems for verification teams. Over the past 20 years, verification has transformed from a single language (Verilog) and tool (simulator) to utilizing many languages (testbench languages, assertion languages, coverage languages, constraint languages), many... » read more

Taming Concurrency
By Brian Bailey - 17 Jan, 2019 - Comments: 2

Concurrency adds complexity for which the industry lacks appropriate tools, and the problem has grown to the point where errors can creep into designs with no easy or consistent way to detect them. In the past, when chips were essentially a single pipeline, this wasn't a problem. In fact, the early pioneers of EDA created a suitable language to describe and contain the necessary concurrency ... » read more

Is Software Necessary?
By Brian Bailey - 27 Aug, 2018 - Comments: 0

Hardware must be capable of running any software. While that might have been a good mantra when chips were relatively simple, it becomes an impossible verification task when dealing with SoCs that contain dozens of deeply embedded processors. When does it become necessary to use production software and what problems can that get you into? When verification targets such as power are added, it... » read more

Abstracting Abstracter Abstractions In Functional Verification
By Neil Johnson - 26 Mar, 2018 - Comments: 0

I heard a clear three-part message during DVCon at the end of February: verification engineers must abstractly embrace the abstract idea of abstracting abstract abstraction through higher levels of abstraction; we overuse the word abstract to emphasize the value of whatever verification technique we happen to be talking about; and the key to new abstractions is using Portable Stimulu... » read more

Three Things You Need To Know To Use The Accellera PSS
By Cadence - 29 Nov, 2017 - Comments: 0

Three primary considerations for adopting the Accellera Portable Stimulus Standard (PSS) are understanding the following: the value and relevance of this standard; the fundamental concepts of PSS modeling, including building blocks, process, and mindset; and PSS portability and how these scenarios can be applied to a specific platform. In this paper, we explore these three topics. To read mo... » read more

Prototypes Proliferate
By Brian Bailey - 02 Oct, 2017 - Comments: 0

Hardware prototyping and [getkc id="30" kc_name="emulation"] have been two sides of the same coin ever since the [gettech id="31071" comment="FPGA"] became a commercial success. Early emulators were all built from FPGAs, and most were used in-circuit, much like prototypes are today. More recently, emulation has become a major piece of the [getkc id="10" kc_name="verification"] flow, to the poin... » read more
