Interconnect Challenges Grow, Tools Lag
By Brian Bailey - 15 Jun, 2020 - Comments: 2

Interconnects are becoming much more problematic as devices shrink and the amount of data being moved around a system continues to rise. This limitation has shown up several times in the past, and it's happening again today. But when the interconnect becomes an issue, it cannot be solved in the same way issues are solved for other aspects of a chip. Typically it results in disruption in how ... » read more

(Artificially) Intelligent Verification
By Brian Bailey - 01 Jun, 2020 - Comments: 1

Functional verification produces a lot of data, , but does that make it suitable for Artificial Intelligence (AI) or Machine Learning (ML)? Experts weigh in about where and how AI can help and what the industry could do to improve the benefits. "It's not necessarily the quantity," says Harry Foster, chief scientist for verification at Mentor, a Siemens Business. "It's the quality that matter... » read more

A Different View On Debugging
By Hagai Arbel - 01 Jun, 2020 - Comments: 0

The classic approach to improve an engineering task that is becoming too complex due to its size and detail is to raise the abstraction of design representation. In this way we plan cities, build aircraft and plan 500M gate SoCs. For example, there is no way an ASIC design could go beyond a few thousand logic gates without shifting abstraction to the Register Transfer Level (RTL) and leveragin... » read more

Capturing Bugs Visually
By Vtool - 24 Apr, 2020 - Comments: 0

This paper presents a new way to comprehend complex scenarios, in order to significantly accelerate bug detection and resolution. By defining a new visual language, which creates interaction vertices between the simulation scenarios and the code structure on a single matrix, we offer a novel way to compare multiple cycles. It enables verification engineers to reach solid conclusions regarding a... » read more

The Debug Problem…
By Hagai Arbel - 23 Apr, 2020 - Comments: 1

While semiconductor verification techniques have evolved considerably over the last 25 years, the debug of design problems found during verification has barely changed. New algorithms including machine learning, visualization approaches, and problem-solving ideas allow a different approach to debugging that saves up to an order of magnitude in debug time. Since the inception of Hardware Desc... » read more

Practical Processor Verification
By Brian Bailey - 23 Apr, 2020 - Comments: 0

Custom processors are making a resurgence, spurred on by the early success of the RISC-V ISA and the ecosystem that is rapidly building around it. But this shift is amid questions about whether processor verification has become a lost art. Years ago custom processors were common. But as the market consolidated around a handful of companies, so did the tools and expertise needed to develop th... » read more

Using Processor Trace At The System Level
By Ann Mutschler - 23 Apr, 2020 - Comments: 0

The race to process more data faster using less power is creating a series of debug challenges at the system level, where developers need to be able to trace interactions across multiple and often heterogeneous processing elements that may function independently of each other. In general, trace is a hardware debug feature that allows the run-time behavior of IP to be monitored. More specific... » read more

Power-Hungry Safety And Security
By Brian Bailey - 09 Apr, 2020 - Comments: 0

There is a price to pay for everything. When it comes to adding safety and security into a device, the costs in terms of power and area can be significant, but if the task is taken seriously, those costs can be managed and minimized. New analysis and implementation tools are coming to market that can also help to keep the costs contained. But it also requires the right mindset. As more indus... » read more

Why It’s So Hard To Create New Processors
By Brian Bailey - 26 Mar, 2020 - Comments: 1

The introduction, and initial success, of the RISC-V processor ISA has reignited interest in the design of custom processors, but the industry is now grappling with how to verify them. The expertise and tools that were once in the market have been consolidated into the hands of the few companies that have been shipping processor chips or IP cores over the past 20 years. Verification of a pro... » read more

The Big Data Revolution Beautiful Servant Or Dangerous Monster?
By Vtool - 25 Mar, 2020 - Comments: 0

The world is experiencing the revolution of information, humanity shifting the hegemony from science onto data. Just as the printing revolution once flooded the world with information, now cybernetic space is engulfing the entire planet with enormous amounts of information particles. We are living in an era where knowledgeability, facts, and big data have completely taken over, and control us a... » read more
