UVM Express

Details

Overview

UVM Express is a collection of techniques, coding styles and UVM usages that are designed to increase the productivity of functional verification. The techniques include raising the abstraction level of tests, writing tests using BFM function and task calls, adding functional coverage, and adding constrained-random stimulus generation. The UVM itself is a powerful class library and associated usage guidelines for creating reusable transaction-level verification environments and components. Unfortunately for many teams, UVM’s reliance on the object-oriented programming (OOP) features of SystemVerilog and advanced features means that the barrier to adoption of UVM is simply too high. UVM Express makes it easier to adopt key pieces of UVM in a much more straightforward manner, while leaving open the opportunity to adopt full UVM in the future.

What You Will Learn

  • How to raise the abstraction level of your test by structuring your environment to use Bus Functional Models (BFMs) using tasks in interfaces to facilitate test writing
  • How to add functional coverage to an existing BFM-based testbench to measure the quality of your existing tests
  • How to add constrained-random stimulus generation to an existing BFM-based testbench to improve the productivity of the test write and improve the overall quality of your test environment.
  • How to instantiate and configure VIP components to simplify the adoption of functional coverage and constrained-random stimulus
  • How to move from initial adoption with UVM Express to a full UVM-based environment

About the Presenter

Verification Technologist

Tom Fitzpatrick is currently a Verification Technologist at Mentor Graphics Corp. where he brings over two decades of design and verification experience to bear on developing advanced verification methodologies, particularly using SystemVerilog, and educating users on how to adopt them. He has been actively involved in the standardization of SystemVerilog, starting with his days as a member of the Superlog language design team at Co-Design Automation through its standardization via Accellera and then the IEEE, where he has served as chair of the 1364 Verilog Working Group, as well as a Technical Champion on the SystemVerilog P1800 Working Group. At Mentor Graphics, Tom was one of the original designers of the Advanced Verification Methodology (AVM), and later the Open Verification Methodology (OVM), and is the editor of Verification Horizons, a quarterly newsletter with approximately 40,000 subscribers. He is a charter member and key contributor to the Accellera Verification IP Technical Subcomittee. He has published multiple articles and technical papers about SystemVerilog, verification methodologies, assertion-based verification, functional coverage, formal verification and other functional verification topics.
