Standard Cell Characterization-3+ Years Experience

-

1. DIFF between NLDM, CCS AND ECSM

2. WHY AND WHAT TYPE OF CONTEXT GDS IS USED FOR CHARACTERIZATION.

3. CHAR SPECIFICATIONS AND HOW IT IS GENERATED

4. HOW INDEX VALUES WERE CALCULATED IN LIBERTIES

5. MILLER CAPACITANCE

6. METHODOLOGY FOR CALCULATING SETUP/HOLD

7. USAGE OF SPECIAL CELLS AND ITS IMPORTANCE AND WHAT ALL THE EXTRA FACTORS THAT NEED TO BE TAKEN CARE WHILE CHARACTERIZING THESE AND WHAT EXTRA ATTRIBUTES WILL SPECIFY THE BEHAVIOUR OF THESE CELLS ( POWER GATERS, ISOLATION, LEVEL SHIFTERS, RETENTIONS, MULTI BIT FLOPS, SYNCRONIZERS)

8. WHY APACHE ?? WHY BOT LIBERTY POWER MODELS

9. METHODOLOGY HOW APACHE POWER CALCULATION IS DIFFERENT FROM LIBERTY POWER CALCULATION.

10. USAGE OF APACHE MODELS AT TOP LEVEL

11. VALIDATION CHECKS FOR LIBERTIES

12. CCS NOISE CALCULATION.

13. HOW THRESHOLD POINTS WERE FIXED 

14. IMPACT OF NEGATIVE DELAY AND ITS SOURCE

15. IS SETUP/HOLD IS ALWAYS POSITIVE ?? IF NOT WHY ?

16. WHY SETUP+HOLD SHOULD ALWAYS BE GREATER THAN 0

Qualcomm Interview (DFT Role)- Fresher

-
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, ...
