Round 2 - Technical 

(8 Questions)

  • Q1. What are the PD inputs and outputs
  • Ans. 

    PD inputs are design specifications and constraints, while outputs are physical layout of the design.

    • Inputs include design specifications, constraints, technology libraries, and floorplan.

    • Outputs include physical layout, placement of components, routing of wires, and design verification.

    • Example: Input - RTL design, clock frequency, power constraints. Output - GDSII layout, timing analysis report.

  • Answered by AI
  • Q2. Describe each stage of PNR flow
  • Ans. 

    PNR flow consists of synthesis, floorplanning, placement, clock tree synthesis, routing, and signoff stages.

    • Synthesis: Convert RTL code to gate-level netlist

    • Floorplanning: Define chip area, core, and I/O locations

    • Placement: Place gates in specific locations to meet timing constraints

    • Clock tree synthesis: Create clock distribution network

    • Routing: Connect gates with wires while considering timing and congestion

    • Signoff: V...

  • Answered by AI
  • Q3. What are the different techniques to minimize congestion?
  • Ans. 

    Techniques to minimize congestion include buffer insertion, wire spreading, and layer assignment.

    • Buffer insertion: Adding buffers to critical paths to improve timing and reduce congestion.

    • Wire spreading: Distributing wires evenly to reduce congestion in specific areas.

    • Layer assignment: Properly assigning different signal layers to reduce congestion on a single layer.

  • Answered by AI
  • Q4. What is the setup and hold time and different techniques to fix the setup and hold time violations?
  • Ans. 

    Setup and hold time are timing constraints in digital circuits. Techniques to fix violations include adjusting clock skew, buffering signals, and optimizing routing.

    • Setup time is the minimum amount of time a data input must be stable before the clock edge for proper operation.

    • Hold time is the minimum amount of time a data input must be stable after the clock edge for proper operation.

    • Techniques to fix setup and hold ti...

  • Q5. What is signal integrity?
  • Ans. 

    Signal integrity refers to the quality of an electrical signal as it travels through a circuit or system.

    • It involves ensuring that the signal remains clear and undistorted from the transmitter to the receiver.

    • Factors affecting signal integrity include impedance matching, noise, crosstalk, and reflections.

    • Signal integrity analysis is crucial in high-speed digital design to prevent data errors and ensure reliable communi...

  • Answered by AI
  • Q6. What is crosstalk and noise and how to fix it?
  • Ans. 

    Crosstalk is unwanted interference between signals on adjacent lines, while noise is random unwanted signals that can degrade performance.

    • Crosstalk occurs when signals on adjacent lines interfere with each other due to coupling effects.

    • Noise is random unwanted signals that can be caused by various sources such as electromagnetic interference or power supply fluctuations.

    • To fix crosstalk, techniques like spacing out lin...

  • Answered by AI
  • Q7. What is clock latency, skew and jitter?
  • Ans. 

    Clock latency is the delay between the clock signal being generated and reaching the destination, skew is the variation in arrival times of the clock signal at different destinations, and jitter is the variation in the period of the clock signal.

    • Clock latency is the delay between the clock signal being generated and reaching the destination.

    • Skew is the variation in arrival times of the clock signal at different destina...

  • Answered by AI
  • Q8. What is useful skew, negative skew and positive skew?
  • Ans. 

    Useful skew, negative skew, and positive skew are terms used in physical design to describe timing constraints.

    • Useful skew refers to intentional delay added to certain paths to meet timing requirements.

    • Negative skew occurs when data arrives later than expected, leading to potential timing violations.

    • Positive skew occurs when data arrives earlier than expected, potentially causing setup time violations.

    • Skew can be adjus...

Round 2 - Technical 

(2 Questions)

  • Q1. Power dissipation Types
  • Q2. Latch up Problem
  • Ans. 

    Latch up is a phenomenon in integrated circuits where a parasitic structure causes a low-impedance path to form, leading to a high current flow.

    • Latch up can occur in CMOS circuits due to the parasitic thyristor formed by the p-n-p-n structure of the MOSFETs.

    • It can be triggered by high voltage spikes or excessive current, causing the parasitic thyristor to turn on and create a short circuit.

    • Latch up can be prevented by ...

(3 Questions)

  • Q1. About latches and flip flops
  • Q2. Diff bw latches and ff
  • Ans. 

    Latches are level-sensitive while flip-flops are edge-triggered. Flip-flops have a clock input while latches do not.

    • Latches are level-sensitive, meaning the output changes as long as the enable signal is active.

    • Flip-flops are edge-triggered, meaning the output changes only on the rising or falling edge of the clock signal.

    • Flip-flops have a clock input which latches do not have.

    • Latches are faster but consume more power ...
