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.
Setup and hold time basic embedded systems - ALU, Memory, control logic moore mealey machine, state transition diagram
Questions were allright - basic ASIC, STA questions.
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?
