Now You Can Automate Latch-Up Verification For 2.5/3D Technologies
By Dina Medhat - 12 Aug, 2021 - Comments: 0

Latch-up is modeled as a short circuit (low-impedance path) that can occur in an integrated circuit (IC). It may lead to destruction due to over-current resulting from interactions between parasitic devices (PNP and NPN). To protect against latch-up conditions, there are two key types of latch-up design rules—fundamental and advanced [1,2]. Fundamental rules are the local latch-up design r... » read more

ASIC/IC Verification Trends With A Focus On Factors Of Silicon Success
By Harry Foster - 08 Jul, 2021 - Comments: 0

At long last we come to the final installment of our four-part series presenting the findings of the Wilson Research Group Functional Verification 2020 study. In this article we discuss verification trends in IC/ASIC language and library adoption, low power management, and verification effectiveness. We then take a deeper dive into two somewhat surprising phenomena revealed in the data: the ... » read more

Beyond The Water Cooler: 2020 Report On IC/ASIC Design And Verification Trends
By Harry Foster - 10 Jun, 2021 - Comments: 0

Verification and design engineers like to talk shop and discuss their experiences and visions. But even though engineers sharing stories around the water cooler (whatever form that takes—conferences, blogs, etc.) does provide all kinds of valuable insights, it doesn’t provide the full picture into the very large and complicated and extremely dynamic global semiconductor industry. To better ... » read more

Trends In FPGA Verification Effort And Technology Adoption
By Harry Foster - 13 May, 2021 - Comments: 0

The more we know about the bigger picture, context, historical and projected trends, or simply how other people do the same thing we do, the more efficiently and successfully we can do our specific jobs. This perspective also informs the EDA industry in how to best assist and sustain the needs of the FPGA and ASIC engineering communities. Providing this kind of information is the reason we c... » read more

Verification Effectiveness In The Face Of FPGA Complexity: The 2020 Wilson Research Group Functional Verification Study
By Harry Foster - 08 Apr, 2021 - Comments: 0

Making informed decisions backed by good data is the key to success in highly competitive, robust markets such as FPGA design and verification. Helping our community in that endeavor is the motivation behind the worldwide Wilson Research Group Functional Verification Study. We also use that information to make sure our research and development efforts continue to deliver the solutions our cu... » read more

An Integrated Approach To Power Domain And CDC Verification
By Kurt Takara - 11 Mar, 2021 - Comments: 0

Reducing power consumption is essential for both mobile and data center applications. Yet it is a challenge to lower power while minimally impacting performance. The solution has been to partition designs into multiple power domains which allow selectively reducing voltage levels or powering off partitions. Traditional low power verification validates only the functional correctness of power... » read more

The Many Flavors Of UPF: Which Is Right For Your Design?
By Madhur Bhargava - 11 Feb, 2021 - Comments: 0

Energy efficient electronic systems require sophisticated power management architectures that present difficult low-power verification challenges. Accellera introduced the Unified Power Format (UPF) standard in 2007 to help engineers deal with these complex issues. To keep pace with the growing complexity of low-power designs, the UPF standard has itself continued to evolve through the relea... » read more

Achieving Physical Reliability Of Electronics With Digital Design
By John Parry - 14 Jan, 2021 - Comments: 0

By John Parry and G.A. (Wendy) Luiten With today’s powerful computational resources, digital design is increasingly used earlier in the design cycle to predict zero-hour nominal performance and to assess reliability. The methodology presented in this article uses a combination of simulation and testing to assess design performance, providing more reliability and increased productivity. ... » read more

Fast, Low-Power Inferencing
By Russell Klein - 10 Dec, 2020 - Comments: 1

Power and performance are often thought of as opposing goals, opposite sides of the same coin if you will. A system can be run really fast, but it will burn a lot of power. Ease up on the accelerator and power consumption goes down, but so does performance. Optimizing for both power and performance is challenging. Inferencing algorithms for Convolutional Neural Networks (CNN) are compute int... » read more

Customizing Low-Power Platforms Using UPF Dynamic Properties
By Progyna Khondkar - 12 Nov, 2020 - Comments: 0

Low power design and verification engineers need a way to continuously probe various dynamic properties of UPF objects in order to monitor the current state of a verification strategy and utilize that information to develop custom low-power verification environments. Unfortunately, there hasn’t been a reliable, formalized way to do this. Since availability of the dynamic properties of unif... » read more
