Q1. Is setup and hold uncertainty values are different
Ans. 
Yes, setup and hold uncertainty values are different in physical design engineering.
• Setup uncertainty is related to the arrival time of the data signal at the input of the flip-flop, while hold uncertainty is related to the removal time of the data signal.

• Setup time is the minimum amount of time the data input must be stable before the clock edge, while hold time is the minimum amount of time the data input must be sta...read more

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 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
