polymorphism in systemverilog testbench

An easier way to demonstrate this would be to not call base.send () because you have to use new for that. %PDF-1.6 % Y*K0 ;r;~.

%%EOF Each course consists of multiple sessionsallowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. If the function display was not declared as 'virtual', then calling a_h.display would always call the defined in class A, regardless of whether or not a_h was storing a handle to an extended object.

If you just want to demonstrate polymorphism, there is no need to call new on the base class.

The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification.

This site uses cookies to improve your user experience and to provide you with content we believe will be of interest to you. Consider this code snippet to understand, By means of inheritance you can reuse previously written classes to extend functionality of your blocks.

- When inheritance is in picture, one can hide parent class properties/methods by declaring same set in extended class as well. These recorded seminars from Verification Academy trainers and users provide examples for adoption of new technologies and how to evolve your verification process. This video explains how we use Object Oriented Programming feature Polymorphism to create SystemVerilog testbench which can generate various random test scenarios to verify the RTL design thoroughly. How do I get a job in ASIC/FPGA verification? 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.

You could do:ext_b = new()b=ext_b;b.send()This is true Polymorphism where you are usign a base class handle to access a derived class's function without having to allocate memory to it..

If we will not declare the fuction as "virtual" then also we can override the function using Inheritance concept.
