Q2. How to fix setup and hold violation
Ans. 
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

Q5. Why does setup and hold ail on same path
Ans. 
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 resul

Q1. How to do grid check and what are the inputs required for gridcheck
Ans. 
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 ali
