Question which were asked on 22nd dec session (doubts clearing session)

  1. Difference between flat and hierarchical design?
  2. What is the need for sanity checks at floorplan stage?
  3. Explanation of flipchip?
  4. How can we decide no of routing layers in a design? Does more no of routing layers beneficial.
  5. Difference between drive strength and fanout.
  6. For specific corner can a path have both setup and hold violation?
  7. Why do we have no of routing layers better or worse?
  8. What is functional ECO?
  9. Difference SDC file as an input to floor planning although we don’t do timing analysis after floor planning?
  10. How to decide max transition on clock and data?
  11. What is RDL layer?
  12. Two clock paths coming from same PLL will always be synchronous or asynchronous? Or are there different conditions attached to it.
  13. Why do we need driving cell for input ports and load for the output ports?
  14. Is there any difference between tie cells and level shifters?
  15. Why setup is only considered for worst case? and Hold for best case? and What will happen if reverse is done?
  16. Explanation regarding capture and launch clock.
  17. Difference between HFNS and CTS.  
  18. how std cells are placed? With complete explanation?
  19. how to resolve unsigned nets in the synthesis stage?
  20. how to resolve max tran and max cap vailotions?
  21. implicite and explicit exceptions in cts stage?
  22. Input files based on Physical Design (Indeep and explain with those files?
  23. Synchronizer Logic With Example?
  24. Frequency divider for 3,4,5,6,7,8?
  25. When we ar eworking  90nm or other tech  how to change  one technology to another technology or else for given technology is fixed we can't  change for a same project
  26. how to fix drc
  27. is drc and crpr related

  5. IEEE Project Domain management in software engineering is distinct from traditional project deveopment in that software projects have a unique lifecycle process that requires multiple rounds of testing, updating, and faculty feedback. A IEEE Domain project Final Year Projects for CSE system development life cycle is essentially a phased project model that defines the organizational constraints of a large-scale systems project. The methods used in a IEEE DOmain Project systems development life cycle strategy Project Centers in India provide clearly defined phases of work to plan, design, test, deploy, and maintain information systems.


    This is enough for me. I want to write software that anyone can use, and virtually everyone who has an internet connected device with a screen can use apps written in JavaScript. JavaScript Training in Chennai JavaScript was used for little more than mouse hover animations and little calculations to make static websites feel more interactive. Let’s assume 90% of all websites using JavaScript use it in a trivial way. That still leaves 150 million substantial JavaScript Training in Chennai JavaScript applications.
