Virtusa Consulting Services Interview Questions and Answers

Reducing setup and hold time requires optimizing timing constraints, minimizing clock skew, and using proper synchronization techniques.

• Optimize timing constraints by adjusting clock frequencies and paths

• Minimize clock skew by balancing clock distribution and using clock tree synthesis

• Use proper synchronization techniques like flip-flops or latches to ensure data stability

• Consider using multi-cycle paths for critical timing paths

Congestion can be reduced by improving public transportation, implementing congestion pricing, promoting telecommuting, and creating carpooling incentives.

• Improve public transportation by expanding routes and increasing frequency

• Implement congestion pricing to discourage driving during peak hours

• Promote telecommuting to reduce the number of vehicles on the road

• Create carpooling incentives such as designated lanes or discounts on tolls

Macros can be placed in a document by using the 'Developer' tab in Microsoft Word.

• Go to the 'Developer' tab in Microsoft Word

• Click on 'Macros'

• Select 'Create' to write a new macro or 'Record' to record a series of actions as a macro

EUMDR is the new regulation replacing MDD for medical devices in the EU.

• EUMDR stands for European Union Medical Device Regulation

• EUMDR has stricter requirements for clinical evidence and post-market surveillance compared to MDD

• EUMDR requires a Unique Device Identification (UDI) system for better traceability

• MDD (Medical Device Directive) was the previous regulation governing medical devices in the EU

Input file for Physical Design is a file containing information needed for the physical implementation of a circuit.

• Input file typically includes information on floorplanning, placement, routing, and timing constraints.

• Examples of input files for Physical Design include LEF/DEF files, Verilog netlists, and technology libraries.

• The input file is crucial for generating the layout of the circuit and ensuring its functionality and performance.

DHF stands for Design History File, which is a compilation of documents that describes the design history of a medical device.

• DHF is a key document required for medical device manufacturers to demonstrate compliance with regulations.

• It includes design inputs, outputs, verification, validation, and changes made throughout the design process.

• Examples of documents included in DHF are design plans, risk analysis, design reviews, and design verification reports.
