Combined, these features provide a powerful, flexible technology and methodology to help you create scalable, reusable and interoperable testbenches. With the ovm at its core, the UVM already embodies years of object-oriented design and methodology experience, all of which can be applied immediately to a UVM project When we commenced work on UVM, Mentor set out to capture documentation of our existing OVM methodology at a fine level of granularity. In the process, we realized that learning a new library and methodology needed to be a dynamic and interactive experience, preferably consumed in small, easily digested spoonfuls. To reinforce each UVM and OVM concept or best practice, we developed many realistic, focused code examples. The end result is the UVM/OVM Online Methodology Cookbook, whose recipes can be adapted and applied in many different ways by our field experts, customers, and partners alike The book you are holding contains excerpts from this online resource, covering many aspects of the UVM and OVm Check out our UVM website to learn much more and join others in finding out how you can leverage the uvm in your specific applications Findusonlineathttp://verificationacademy.com/cookbook Uvm/ovMDocumentation-copyright(c)2012MentorGraphicsCorporation-http://verificationacademy.com/uvm-ovm Cookbook/Acknowledgements Cookbook/Acknowledgements UVM/OVM Cookbook authors Gordon Allan Mike baird Rich edelman Adam erickson Michael horn · Mark pryer Adam rose Kurt schwartz We acknowledge the valuable contributions of all our extended team of contributors and reviewers, and those who help deploy our methodology ideas to our customers, including: Alain Goner, Allan Crone, Bahaa Osman, Dave rich, Eric Horton, Gehan Mostafa, Graeme Jessiman, Hans van der Schoot, Hager Fathy, Jennifer Adams, John Carroll, John Amouroux, Jason Polychronopoulos, John Stickley, Nigel Elliot, Peet James, Ray Salemi, Shashi Bhutada, Tim Corcoran and Tom Fitzpatrick Uvm/ovMDocumentation-copyright(c)2012MentorGraphicsCorporation-http://verificationacademy.com/uvm-ovm Testbench architecture Testbench This chapter covers the basics and details of uVm testbench architecture, construction and leads into other chapters covering each of the constituent parts of a typical UVM testbench Testbench Chapter contents Testbench(this page)-top-level introduction into testbench architecture UVM-style Testbench/Build -testbench hierarchy construction in the UVM build phase Testbench/Blocklevel -architecture of a unit-level uvm test environment Testbench/IntegrationLevel-example architecture of vertical reuse testbench gent - architecture of a single interface agent UVM Phases-execution phases in an UVM testbench component UVM Factory -machinery for manufacture of configurable objects Topic overview How an uVm testbench differs from a traditional module based testbench In Verilog or VHDL, a testbench consists of a hierarchy of modules containing testbench code that are connected to the design under test (DUT). The modules contain stimulus and response checking code which is loaded into simulator memory along with the dut at the beginning of the simulation and is present for the duration of the simulation Therefore, the classic Verilog testbench wrapped around a dut consists of what are known as static objects System Verilog builds on top of verilog by adding abstract language constructs targetted at helping the verification process. One of the key additions to the language was the class. System Verilog classes allow Object Orientated Programming(OoP)techniques to be applied to testbenches The UVM itself is a library of base classes which facilitate the creation of structured testbenches using code which is open source and can be run on any System Verilog IEEE 1800 simulator Like classes in any other OOP language such as C++ and Java, System Verilog class definitions are templates for an object that is constructed in memory. Once created, that object persists in memory until it is de-referenced and garbage collected by an automatic background process. The class template defines the members of the class which can either be data variables or methods. In System Verilog, the methods can either be functions which are non-time consuming, or tasks which can consume time. Since a class object has to be constructed before it exists in memory the creation of a class hierarchy in a System Verilog testbench has to be initiated from a module since a module is a static object that is present at the beginning of the simulation. For the same reason, a class cannot contain a module. Classes are referred to as dynamic objects because they can come and go during the life time of a simulation //Example to show how a class is constructed from within a static object (a module) Uvm/ovMDocumentation-copyright(c)2012MentorGraphicsCorporation-http://verificationacademy.com/uvm-ovm Testbench // Example class that contains a message and some convenience methods lass example string messagei function void set_message(string ip__string)i message irstring endfanction: set message function void princ ()i display essage) endfanction: print dcl // Module that uses the class class is constructed, used and dereferenced // i the initial block, after the simulation starts module thi example C;// Null handle after elaboration initial begin C= new()i// Handle points to c object in memory C se- message("This object has been created")i #10; C. print ()i C=nulli //C has been dereferenced, object can be garbage collected ndmodule tr Uvm/ovMDocumentation-copyright(c)2012MentorGraphicsCorporation-http://verificationacademy.com/uvm-ovm
