Verification Tools Straining To Keep Up
By Brian Bailey - 01 Jul, 2024 - Comments: 0

Verification engineers are the unsung heroes of the semiconductor industry, but they are at a breaking point and desperately in need of modern tools and flows to deal with the rapidly increasing pressures. Verification is no longer just about ensuring that functionality is faithfully represented in an implementation. That alone is an insolvable task, but verification has taken on many new re... » read more

Accelerate Test Regressions with Synopsys VIP Using Dynamic Test Loading in VCS
By Synopsys - 27 Jun, 2024 - Comments: 0

Functional verification ensures that a design meets its specification requirements. The initial 80% of the verification process significantly impacts the time needed to complete the final 20%, which involves extensive test scenarios and regression testing, often consuming substantial engineering resources. Typically, the desired scenario emerges late in the test case, often in the last minutes ... » read more

Paradigms Of Large Language Model Applications In Functional Verification
By Siemens EDA - 03 Apr, 2024 - Comments: 0

This paper presents a comprehensive literature review for applying large language models (LLM) in multiple aspects of functional verification. Despite the promising advancements offered by this new technology, it is essential to be aware of the inherent limitations of LLMs, especially hallucination that may lead to incorrect predictions. To ensure the quality of LLM outputs, four safeguarding p... » read more

Glitch Power Issues Grow At Advanced Nodes
By Ann Mutschler - 11 Jan, 2024 - Comments: 0

An estimated 20% to 40% of total power is being wasted due to glitch in some of the most advanced and complex chip designs, and at this point there is no single best approach for how and when to address it, and mixed information about how effective those solutions can be. Glitch power is not a new phenomenon. DSP architects and design engineers are well-versed in the power wasted by long, sl... » read more

The Limits Of AI-Generated Models
By Brian Bailey - 26 Oct, 2023 - Comments: 2

In several recent stories, the subject of models has come up, and one recurrent theme is that AI may be able to help us generate models of a required abstraction. While this may be true in some cases, it is very dangerous in others. If we generalize, AI should be good for any model where the results are predominantly continuous, but discontinuities create problems. Unless those are found and... » read more

A Survey Of Machine Learning Applications In Functional Verification
By Siemens EDA - 02 Aug, 2023 - Comments: 0

Functional verification is computationally and data-intensive by nature, making it a natural target of machine learning applications. This paper provides a comprehensive and up-to-date analysis of FV problems addressable by ML. Among the various ML techniques and algorithms, several emerging ones have demonstrated outstanding potential in FV. Yet despite the promising research results, criti... » read more

New Technology Accelerates Multi-Die System Simulation
By Taruna Reddy - 27 Jul, 2023 - Comments: 0

AI-powered chatbots. Robotic manufacturing equipment. Self-driving cars. Bandwidth-intensive applications like these are flourishing—and driving the move from monolithic system-on-chips (SoCs) to multi-die systems. By integrating multiple dies, or chiplets, into a single package, designers can achieve scaling of system functionality at reduced risk and with faster time to market. Multi-die... » read more

The True Cost Of Software Changes
By Brian Bailey - 22 Jun, 2023 - Comments: 2

Safety and security are considered to be important in a growing number of markets and applications. Guidelines are put in place for the processes used to develop either the hardware or the software, but what they seem to ignore is that neither exists in a vacuum. They form a system when put together. Back when I was developing tools for hardware-software co-verification, there were fairly co... » read more
