711 physical design interview questions shared by candidates
Basic of Digital VLSI, digital apti Questions puzzles like how you build complex gates using simple nand/muxes about inverter cross sections, physical design some questions on floorplanning delay calulation go throguh any DVLSI good book or video lectures.
Basics of APR Flow
How do you fix setup and hold violations.
Describe how you would redesign a rectangle on plane x,y to increase its area by a certain value (square of x) while keeping its center the same
how to solve setup violation? What the solution would impact on the other part of the design? how to deal with the SI issue? Clearly know about the calculation of setup time, or min clock period What is OCV on timing check？how to calculate? What is the CPPR?
1.Inverted temperature effect on STA. the question was based on temperature effects on delay below 65nm technology. how STA works under those conditions at different corners. 2. An interesting question about how latency affects jitter. 3. Maximums kew allowed when lock up latches are used. 4. OCV n questions based on it. 5. CRPR. 6. how does a cell get min n max delay? 7. spef file contents, questions about star-rd extractor working. 8. Internship exp based questions.
Implement integer division
1. Toughest question asked (in my opinion, as it required creativity and knowledge to answer) was on writing the following function in Verilog: W = .5X + .25Y Where W was an output, and X/Y are inputs. 2. If X/Y where 4 bits each, what is maximum output number possible?
