  1. When will you use a latch and a flipflop in a sequential design?

  2. Design a 1-bit fulladder using a decoder and 2 “or” gates?

  3. You have a circuit operating at 20 MHz and 5 volt supply. What would you do to reduce the power consumption in the circuit-reduce the operating frequency of 20Mhz or reduce the power supply of 5Volts and why?

  4. In a nmos transistor, how does the current flows from drain to source in saturation region when the channel is pinched off?

  5. In a SRAM circuit, how do you design the precharge and how do you size it?

  6. In a PLL, what elements (like XOR gates or Flipflops) can be used to design the phase detector?

  7. While synthesis of a design using synopsys design compiler, why do you specify input and output delays?

  8. What difference do you see in the timing reports for a propogated clock and an ideal clock?

  9. What is timeborrowing related to Static timing anaylsis in Primetime?
