• A Generic UVM Scoreboard

  Article - Nov 01, 2015 by Jacob Andersen, Kevin Seffensen, Peter Jensen - SyoSil ApS

  All UVM engineers employ scoreboarding for checking DUT/reference model behavior, but only few spend their time wisely by employing an existing scoreboard architecture. The main reason is that existing frameworks have inadequately served user needs and have failed to improve user effectiveness in the debug situation. This article presents a better UVM scoreboard framework, focusing on scalability, architectural separation and connectivity to foreign environments.

• Verify Thy Verifyer

  Article - Mar 01, 2020 by Srinivasan Venkataramanan, Ajeetha Kumari - VerifWorks

  Design Verification is a field that requires a lot of thinking and equally a lot of coding. Tighter time-to-market adds a lot of schedule pressure to the teams coding those testbenches and test cases. The advent of UVM (Universal Verification Methodology) as the standard framework, has helped the industry make good progress in terms of structured testbenches. One of the primary objectives of UVM is to build robust, reusable testbenches.

• UVM 1800.2 & The New and Improved UVM Cookbook

  Webinar - Sep 11, 2018 by Tom Fitzpatrick

  This session will start with an overview of the changes in UVM 1800.2 from UVM 1.2 and 1.1d so you can be prepared to embrace the new Standard.

• DO-254 Compliant UVM VIP Development

  Article - Mar 02, 2016 by Verification Horizons

  Late 2014, we found ourselves in a Project to develop a custom interconnect UVM Compliant VIP. Not only was there a need to develop a custom UVM VIP, but there was a need to plug this to a DUT which has a PCIe and an Avalon Streaming interface on it and perform the advance verification using our custom UVM VIP.

• Celebrating 10 Years of the UVM

  Article - Mar 03, 2021 by Mark Peryer

  Version 1.0 of the UVM class library was released by Accellera at the end of February 2011, the result of a unique collaborative effort between fierce competitors (Siemens EDA, formerly Mentor Graphics, Cadence, and Synopsys) and a small number of activist user companies. The objective was to provide an industry standard SystemVerilog based verification methodology.

• The Verification Academy Patterns Library

  Article - Mar 02, 2016 by Harry Foster

  The literature for many of today’s testbench verification methodologies (such as UVM) often reference various software or object-oriented related patterns in their discussions. For example, the UVM Cookbook (available out on the Verification Academy) references the observe pattern when discussing the Analysis Port.

• Top Five Reasons Why Every DV Engineer Will Love the Latest SystemVerilog 2012 Features

  Article - Jun 12, 2014 by Ajeetha Kumari, Srinivasan Venkataramanan - CVC Pvt. Ltd.

  SystemVerilog has become the most widely deployed Verification language over the last several years. Starting with the early Accellera release of 3.1a standard, the first IEEE 1800-2005 standard fueled the widespread adoption in tools and user base. Since 2005 there is no look-back to this "all encompassing" standard that tries to satisfy and do more for RTL Designers and Verification engineers alike.

• Unit Testing Your Way to a Reliable Testbench

  Article - Sep 02, 2015 by Neil Johnson

  Writing tests, particularly unit tests, can be a tedious chore. More tedious - not to mention frustrating - is debugging testbench code as project schedules tighten and release pressure builds. With quality being a non-negotiable aspect of hardware development, verification is a pay-me-now or pay-me-later activity that cannot be avoided. Building and running unit tests has a cost, but there is a greater cost of not unit testing. Unit testing is a proactive pay now technique that helps avoid running up debts that become much more expensive to pay later.

• How Static and Dynamic Failure Analysis Can Improve Productivity in the Assessment of Functional Safety

  Article - Oct 04, 2018 by Verification Horizons

  Integrated circuits used in high-reliability applications must demonstrate low failure rates and high levels of fault detection coverage. Safety Integrity Level (SIL) metrics indicated by the general IEC 61508 standard and the derived Automotive Safety Integrity Level (ASIL) specified by the ISO 26262 standard specify specific failure (FIT) rates and fault coverage metrics (e.g., SPFM and LFM) that must met.

• Reflections on Users’ Experiences with SVA

  Article - Mar 02, 2022 by Ben Cohen

  In my years of contributions to the Verification Academy SystemVerilog Forum, I have seen trends in real users’ difficulties in the application of assertions, the expression of the requirements, the angle of attacks for verification, the misunderstandings of how SVA works, and the confusion as to which SVA option to use.

• Increased Efficiency with Questa VRM and Jenkins Continuous Integration

  Article - Jan 17, 2017 by Thom Ellis

  For all the incredible technological advances to date, no one has found a way to generate additional time. Consequently, there never seems to be enough of it. Since time cannot be created, it is utterly important to ensure that it is spent as wisely as possible. Applying automation to common tasks and identifying problems earlier are just two proven ways to best utilize time during the verification process.

• The RISC-V Verification Interface (RVVI) – Test Infrastructure and Methodology Guidelines

  Article - Feb 24, 2023 by Aimee Sutton, Lee Moore, Kevin McDermott - Imperas Software

  The open standard ISA of RISC-V is at the forefront of a new wave of design innovation. The flexibility to configure and optimize a processor for the unique target application requirements has a lot of appeal in emerging and established markets alike. RISC-V can address the full range of compute requirements such as an entry-level microcontroller, a support processor, right up to the state-of-the-art processor arrays with vector extensions for advanced AI applications and HPC.

• Certus™ Silicon Debug: Don’t Prototype Without It

  Article - Mar 07, 2016 by Verification Horizons

  FPGA PROTOTYPE RUNNING—NOW WHAT? Well done team; we've managed to get 100's of millions of gates of FPGA-hostile RTL running at 10MHz split across a dozen FPGAs. Now what? The first SoC silicon arrives in a few months so let's get going with integrating our software with the hardware, and testing the heck out of it. For that, we'll need to really understand what's going on inside all those FPGAs. Ah, there's the rub.
