Infineon Interview Questions- General for freshers

-

1. Basic digital electronics, mostly based on timers, counters and FFs.

2. Microcontroller- ARM architecture/ 8051

3. Interrupts,  NVICs, memory organization in uC, watchdog timers, PWMs etc.

4. Basic C programming, like masking, nested loops, bitwise operations

5. Op-Amps and their usage in uC

6. ADC and DACs internal structure and working 

7. Any projects you've worked on!

8. Communication protocols like CAN, IIC, SPI, UART etc. And their internal functioning!

9. Clocks - difference between PLL, FLL, and how to create clock divider circuit (both odd division and even) and how to upscale 

10. Power electronics - buck, boost, LDOs and their internal working! 

11. Ripple currents and use of inductors, also, decoupling capacitors

12. Difference between single ended lines and differential pairs and why we use them

13. Some basic validation procedure including PVTF flow

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, ...
