Synapse Design Physical Design Engineer Interview Questions and Answers

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...read more

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

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...read more
