I was interviewed in Oct 2024.
The PD flow is the process of designing the physical layout of integrated circuits.
Initial floorplanning to determine the placement of blocks and macros
Placement and optimization of standard cells
Routing of interconnects to connect the various components
Physical verification to ensure design rules are met
Timing closure to meet performance targets
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
My domain expertise is in physical design engineering, specifically in the areas of floorplanning, placement, routing, and timing closure.

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
I applied via LinkedIn and was interviewed in Nov 2024. There was 1 interview round.
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
Analyzing the powergrid involves studying its components, performance, and efficiency.
Start by examining the overall layout and structure of the powergrid
Analyze the distribution of power sources, transmission lines, and substations
Evaluate the efficiency of the powergrid in terms of energy loss and voltage stability
Use simulation software to model different scenarios and optimize the powergrid
Consider factors like ren...
