Q1. What are storage class
Ans. 
Storage classes in C specify the scope and lifetime of variables.
• Storage classes include auto, register, static, and extern.

• Auto variables are local to a block and have automatic storage duration.

• Register variables are stored in CPU registers for faster access.

• Static variables retain their value between function calls.

• Extern variables are declared in one file and can be used in another file.

Q2. Explain structure program
Ans. 
A structure program is a program that uses structures to group related data together.
• Structures in C programming allow you to group related data together under one name.

• You can define a structure using the 'struct' keyword.

• Structures can contain different data types, including int, float, char, and even other structures.

• You can access the members of a structure using the dot operator.

• Example: struct employee { int id; ...read more

Q1. What is que in sv ?
Ans. 
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().

Q2. What is mailbox
Ans. 
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

Q3. What is delay inter and intera
Ans. 
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.

Q4. What is constraint
Ans. 
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

Q5. What is oops related
Ans. 
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

Q1. What is binary coded decimal?
Ans. 
Binary Coded Decimal (BCD) is a way of representing decimal numbers using a binary code.
• BCD uses four bits to represent each decimal digit.

• Each decimal digit is represented by its binary equivalent.

• For example, the decimal number 25 is represented in BCD as 0010 0101.

Q2. How keyboard mapping works in a microcontroller?
Ans. 
Keyboard mapping in a microcontroller involves assigning specific key codes to each key on the keyboard.
• Keyboard mapping is typically done using a lookup table that maps physical key presses to corresponding key codes.

• The microcontroller reads the key code when a key is pressed and sends it to the computer for processing.

• Keyboards may use different mapping standards such as ASCII or HID.

• Custom keyboard mappings can als...read more
