There were in total 5 rounds (4 technical rounds + 1 HR round) First round: 1. What do I understand by DFT and the need for DFT? 2. What are scan flip flops? 3. What are the different simulation techniques for testing? What do you infer from transient delay simulation? 4. A circuit with several and-or gates was given, need to identify the input test vector for detecting a slow-to-rise fault at a particular net. 5. What is BIST?  5b. What are the different techniques used for compaction?  6. What is boundary-scan standard? (JTAG) 7. How do you rank various sorting algorithms? (insertion, bubble, etc) 8. What do you understand from hazards in a processor design? How did you overcome control hazards? 9. What happens in a deep pipelined system? (Performance related, flushing all stages of the pipeline when branch prediction fails. Increased latency). 10. Write a Verilog code for a RAM, let the address space be a parameter. 11. Are you familiar with writing scripts in- bash, PERL, ...
