System verilog object oriented concepts
Share This Articale:

What is Object oriented programming :

  1. OOP is object oriented programming
  2. Classes form the base of OOP programming
  3. Encapsulation - OOP binds data & function together
  4. Inheritance –extend the functionality of existing objects
  5. Polymorphism – wait until runtime to bind data with functions
  6. OOP breaks a testbench into blocks that work together to accomplish the verification goal

Why Object oriented programming :

  1. Highly abstract system level modelling
  2. Classes are intended for verification
  3. Classes are easily reused and extended
  4. Data security
  5. Classes are dynamic in nature
  6. Easy debugging, one class at a time

What is Inheritence :

  1. Inheritance is to reuse the existing codev
  2. Inheritance allows to add new
    1. Data members(properties)
    2. New Methods
  3. Inheritance is to share code between classes

What is Advantage of Inheritence :

  1. Common code can be grouped into one class
  2. No need to modify the existing classes
  3. Add new features to existing class by means of new derived classes
  4. Easy debug & easy to maintain the code base
