    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

UVM Framework

UVM Framework

UVM Framework is a combination of a class library and a code generator, delivered as part of the Questa® Verification Solution, that enables you to build a UVM testbench within an hour. Providing an architecture and reuse methodology, it allows verification teams, whether they are experienced or new to UVM, to assemble operational UVM testbenches, including industry-standard Questa VIP components, freeing the team to focus on verifying product features. The UVM testbenches developed with UVM Framework are also compatible with our Veloce® emulator.

Slaying the UVM Reuse Dragon

Authors:
  • Mike Baird - WHDL
  • Bob Oden - Mentor Graphics

Abstract:

With larger and more complex designs the gap between design and verification has grown larger. Because of this the reuse of the testbench both in new projects and within the same project has become very desirable. One of the "promises" of UVM is achieving such reuse. However, in reality, UVM reuse has been limited. This paper identifies the issues that affect UVM reuse and strategies for achieving reuse. A UVM reuse methodology will be presented that provides reuse of components from one testbench to another and within the same testbench from block to chip level.

  Slaying the UVM Reuse Dragon - Issues and Strategies for Achieving UVM

A Simplified and Reusable UVM Config DB Methodology

Author:
  • Bob Oden - Mentor Graphics

Motivation:

  • Provide a mechanism for sharing resources within a simulation that provides features needed by architects and simplicity needed by test writers.
  • Architects need a mechanism that can allow resource access by hierarchy and general scope.
  • Test writers need access to simulation resources while treating environment as a black box.
