10+ Accenture Interview Questions and Answers

Algorithm to find first two numbers in an array for a given sum.

• Loop through the array and check if the difference between the sum and each element exists in the array.

• Use a hash table to store the elements and their indices for faster lookup.

Setup and hold violations can be fixed by adjusting timing constraints, optimizing clock tree, and redesigning critical paths.

• Adjust timing constraints to allow more time for signals to propagate

• Optimize clock tree to reduce clock skew and improve timing

• Redesign critical paths by adding buffers or restructuring logic

• Use ECO (Engineering Change Order) to make necessary changes without redoing the entire design

Setup and hold time violations can occur on the same path due to different reasons.

• Timing violations can occur due to variations in process, voltage, and temperature (PVT)

• Clock skew between different paths can lead to setup and hold violations on the same path

• Issues with clock tree synthesis or routing can also contribute to setup and hold time violations

• Improper constraints or incorrect timing analysis setup can result in violations on the same path

Design a data pipeline for a given situation

• Identify data sources and their formats

• Choose appropriate data storage and processing technologies

• Define data processing steps and their order

• Ensure data quality and consistency

• Implement data validation and error handling

• Monitor and optimize pipeline performance

Grid check is a process to verify the accuracy of a grid system in a design.

• Grid check involves measuring the spacing between grid lines to ensure they meet the specified dimensions.

• Inputs required for grid check include grid line spacing, grid line thickness, and overall grid dimensions.

• Grid check can be done using tools like rulers, calipers, or specialized grid check templates.

• Grid check is important in ensuring alignment and consistency in a design layout.
