RTL Glitch Verification

Article - Jun 29, 2018 by Ajay Daga - FishTail Design Automation

It is important that certain timing endpoints on a design are safe from glitches. For example, it is necessary that an asynchronous reset never have a glitch that momentarily resets a flop. It is also necessary that multi-cycle paths are safe from glitches, i.e., it should not be the case that while a cycle accurate simulation of the RTL shows correct multi-cycle behavior, once delays are accounted for a glitch can propagate along the path resulting in a single-cycle path.
UVM-based Verification of a RISC-V Processor Core Using a Golden Predictor Model and a Configuration Layer

Article - Jun 29, 2018 by Marcela Zachariášová, Luboš Moravec - Codasip Ltd.

In this article, Codasip and Siemens EDA aim to describe their methodology of effective verification of RISC-V processors, based on a combination of standard techniques, such as UVM and emulation, and new concepts that focus on the specifics of the RISC-V verification, such as configuration layer, golden predictor model, and FlexMem approach.
Virtual Method Upcasting & Downcasting And Their Use In UVM

Resource (Slides (.PDF)) - Jun 25, 2018 by Cliff Cummings

This session shows how upcasting and downcasting work and how they are frequently used in UVM testbench environments.
Virtual Method Upcasting & Downcasting And Their Use In UVM

Conference - Jun 25, 2018 by Cliff Cummings

"Upcasting is casting to a supertype, while downcasting is casting to a subtype. Upcasting is always allowed, but downcasting involves a type check … and can throw a ClassCastException" This session shows how upcasting and downcasting work and how they are frequently used in UVM testbench environments.
What is Formal, and How It Works Under-the-Hood

Track - May 14, 2018 by Doug Smith

It’s common knowledge that formal property verification – “formal”, for short – delivers exhaustive results. In a nutshell, formal tools statically analyze a design’s behavior with respect to a given set of properties, exhaustively exploring all possible input sequences in a breadth-first search manner to uncover design errors that would otherwise be missed.
Instant Formal Expert

Session - May 14, 2018 by Dr. Jeremy Levitt

What are formal property checking engines and how do they work? Why are they incredibly powerful for some properties, but not so good for others? What's the state of the art and what's coming in the near future? In this session, we'll review the fundamentals as well as the recent breakthroughs that are driving advances in performance and capacity. Join us to instantly become a formal expert!
