Intel Interview Questions and Answers

VLSI flow involves a series of steps to design integrated circuits from specifications to fabrication.

• Specification: Define the requirements and functionality of the circuit.

• Architecture Design: Create a high-level design, including block diagrams.

• Logic Design: Develop the circuit using logic gates and HDL (e.g., Verilog, VHDL).

• Synthesis: Convert HDL code into a gate-level netlist.

• Placement: Arrange the components...read more

The ARM Cortex-A series is a popular microarchitecture designed for high performance and energy efficiency in mobile devices.

• Designed for mobile and embedded systems, balancing performance and power consumption.

• Utilizes a pipeline architecture to improve instruction throughput.

• Supports advanced features like out-of-order execution and branch prediction.

• Examples include Cortex-A53 and Cortex-A72, widely used in sma...read more

Quick signoff checks ensure design integrity and compliance before finalizing physical layouts in semiconductor design.

• Design Rule Check (DRC): Ensures layout adheres to manufacturing rules, e.g., minimum spacing between metal layers.

• Layout Versus Schematic (LVS): Confirms that the physical layout matches the intended circuit design, e.g., checking transistor connections.

• Electrical Rule Check (ERC): Validates elec...read more

Basic rework of a PCB involves repairing or modifying the board to ensure proper functionality and reliability.

• Identify the faulty components using testing equipment like multimeters.

• Desolder defective components using a soldering iron or desoldering pump.

• Replace with new components, ensuring correct orientation and placement.

• Resolder connections carefully to avoid shorts or cold joints.

• Test the PCB after rework t...read more

OOP in C++ is based on concepts like encapsulation, inheritance, polymorphism, and abstraction for better code organization.

• Encapsulation: Bundling data and methods in classes. Example: class Car { private: int speed; public: void setSpeed(int s) { speed = s; }};

• Inheritance: Deriving new classes from existing ones. Example: class ElectricCar : public Car {}; // ElectricCar inherits from Car

• Polymorphism: Ability to...read more

SPC is used to monitor and improve yield by analyzing process data to detect variations and make adjustments.

• SPC involves collecting data on key process parameters and using statistical tools to analyze trends and patterns.

• By monitoring variations in the process, SPC helps identify potential issues before they impact yield.

• SPC allows for real-time adjustments to be made to the process to maintain or improve yield ...read more
