Silicon Labs Physical Design Engineer Interview Questions and Answers

Q1. What is an ICG? How would you use it in the design?
Ans. 
ICG stands for Inter-Chip Global. It is a network that connects multiple chips in a system.
• ICG is used to transfer data between different chips in a system

• It helps in reducing the number of wires required for communication between chips

• ICG can be used in various design aspects such as clock distribution, power management, and data transfer

• Example: In a multi-chip system, ICG can be used to transfer clock signals from o

Q2. How will MSCTS help at SOC level CTS
Ans. 
MSCTS can help in achieving better clock distribution and reducing skew at SOC level CTS.
• MSCTS (Multi-Source Clock Tree Synthesis) can optimize the clock tree for better skew and jitter performance.

• It can also help in reducing power consumption by optimizing the clock network.

• MSCTS can handle multiple clock sources and ensure proper synchronization.

• It can also help in meeting timing constraints and reducing clock tree ...read more

Q2. How will you fix setup and hold time when both are violating at the same time.
Ans. 
Fixing setup and hold time violations simultaneously requires adjusting clock timing and/or data path delays.
• Identify the critical path causing the violations

• Adjust the clock timing to meet setup and hold requirements

• Adjust the data path delays to meet setup and hold requirements

• Use tools like static timing analysis and delay calculation to determine necessary adjustments

• Iteratively adjust timing and delays until viola
