Hexaware Technologies Verification Specialist Interview Questions and Answers

Que in SystemVerilog (SV) is a built-in data type used for creating queues.

• Queues are dynamic arrays that can grow or shrink in size during simulation.

• Queues can store elements of any data type.

• Elements can be added to the end of the queue using the built-in methods like push_back().

• Elements can be removed from the front of the queue using the built-in methods like pop_front().

A mailbox is a data structure used for communication between different processes or threads in a computer system.

• Mailboxes are typically used in multi-threaded or multi-processor systems to pass messages between different entities.

• They provide a way for processes to communicate without directly accessing each other's memory.

• Mailboxes can be implemented using queues, shared memory, or other mechanisms depending on the s

Delay inter and intra refer to delays within and between different components or systems.

• Delay inter refers to delays between different components or systems.

• Delay intra refers to delays within the same component or system.

• Example: Delay inter can occur when data is transferred between a CPU and memory.

• Example: Delay intra can occur within a CPU due to processing time.

Constraints in verification engineering are conditions or limitations imposed on the design or testbench to ensure certain properties are met.

• Constraints are used to restrict the possible values of variables or signals in a design or testbench.

• They help in verifying specific behaviors or scenarios within the design.

• Examples include setting timing constraints for signal propagation or limiting the range of input values

Object-oriented programming concepts such as classes, objects, inheritance, encapsulation, and polymorphism.

• Classes: Blueprint for creating objects with attributes and methods.

• Objects: Instances of classes that contain data and behavior.

• Inheritance: Ability for a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism:...read more
