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...
Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during compilation.
Variables declared with 'var' are hoisted, but their initialization is not. Example: console.log(a); var a = 5; // undefined
Function declarations are fully hoisted, allowing them to be called before their definition. Example: greet(); function greet() { console.log('Hello');...
let, const, and var are JavaScript keywords for variable declaration with different scopes and mutability.
var: Function-scoped or globally-scoped, can be redeclared and updated. Example: var x = 10; x = 20;
let: Block-scoped, can be updated but not redeclared in the same scope. Example: let y = 10; y = 20; // valid
const: Block-scoped, cannot be updated or redeclared. Must be initialized at declaration. Example: con...
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...
The graphics pipeline is a sequence of steps that transforms 3D models into 2D images on the screen.
1. Vertex Processing: Transforms 3D coordinates into 2D space (e.g., applying transformations like translation, rotation).
2. Clipping: Removes parts of objects outside the viewable area to optimize rendering.
3. Rasterization: Converts vector graphics into pixels, determining which pixels are affected by the shapes.

Connecting an HDMI device triggers OS interrupts for detection and configuration.
HDMI connection generates a hardware interrupt to notify the OS.
The OS identifies the connected device type (e.g., monitor, TV).
Drivers are loaded or configured based on the device capabilities.
Resolution and refresh rate settings may be adjusted automatically.
User notifications may appear, indicating the new display settings.
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 ...
Common defects in semiconductor fabrication process
Contamination: Foreign particles or impurities can cause defects in the semiconductor material.
Oxide Breakdown: Breakdown of the insulating oxide layer can lead to short circuits.
Photoresist Issues: Problems with the photoresist material can result in inaccurate patterning.
Etching Errors: Improper etching can cause damage to the semiconductor layers.

A compiler translates high-level programming code into machine code for execution by a computer.
Lexical Analysis: Breaks code into tokens (e.g., keywords, identifiers).
Syntax Analysis: Checks tokens against grammar rules (e.g., parsing expressions).
Semantic Analysis: Ensures logical consistency (e.g., type checking).
Optimization: Improves code efficiency (e.g., removing dead code).
Code Generation: Converts optimiz...
Computer cache performance refers to the efficiency of the cache memory in storing and retrieving data for the CPU.
Cache performance is measured by hit rate, miss rate, and latency.
A higher hit rate indicates better performance as more data is found in the cache.
Cache misses result in slower performance as data needs to be retrieved from main memory.
Latency refers to the time it takes to access data in the cache.

6 Questions
- Q1. Draw a domino logic circuit
- Ans.
A domino logic circuit is a type of digital circuit that uses a chain of inverters to propagate a signal.
A domino logic circuit consists of a chain of inverters connected in series.
The output of each inverter is connected to the input of the next inverter.
The input signal is applied to the first inverter in the chain.
The output of the last inverter in the chain is the output of the circuit.
Domino logic circuits are fas...
- Q2. How to speed up a circuit. Can voltage scaling be helpful
- Ans.
Yes, voltage scaling can help speed up a circuit by increasing the voltage to improve signal propagation.
Increasing the voltage can reduce the resistance and capacitance effects, leading to faster signal propagation.
Voltage scaling can also increase the switching speed of transistors, improving overall circuit performance.
However, higher voltage levels may also increase power consumption and generate more heat, requiri...
- Q3. Static timing analysis. Asked to write equation for a circuit with 2 flipflops with a latch in middle(latch clock has a delay from FF clock). Concept of time borrowing
- Ans.
Static timing analysis involves calculating timing constraints in circuits with flip-flops and latches to ensure correct operation.
Static timing analysis checks timing paths between flip-flops and latches.
Time borrowing allows a latch to hold data longer than its clock period.
Example: If FF1 outputs to a latch, and the latch has a delay, ensure FF1's setup time is met.
Consider clock skew and latch delay when calculatin...
- Q4. Transistor level designs for simple logic gates
- Ans.
Transistor level designs involve using transistors to create simple logic gates.
Transistors can be used to create logic gates such as AND, OR, and NOT gates.
In an AND gate, two transistors are connected in series.
In an OR gate, two transistors are connected in parallel.
In a NOT gate, a single transistor is used.
Logic gates can be combined to create more complex circuits.
- Q5. Why Intel?
- Ans.
Intel is a global leader in semiconductor technology, offering innovative solutions and a strong focus on research and development.
Intel has a strong reputation for cutting-edge technology and innovation
Intel invests heavily in research and development, providing opportunities for growth and learning
Intel offers a diverse range of products and services, allowing for a variety of projects and challenges
