Hardware Design Engineer interview questions

TYPES OF TRANSISTORS?, WORKING OF BALLAST & STARTER?

Why don't we use just one NMOS or PMOS transistor as a transmission gate?

How can you model a SRAM at RTL Level?

What happens if we increase the number of contacts or via from one metal layer to the next?

For a NMOS transistor acting as a pass transistor, say the gate is connected to VDD, give the output for a square pulse input going from 0 to VDD

Draw a transistor level two input NAND gate. Explain its sizing (a) considering Vth (b) for equal rise and fall times

What is Noise Margin? Explain the procedure to determine Noise Margin

What's the difference between Testing & Verification?

Who did the hardware design for Square?

What stands for "V" in "VHDL" (HDL= Hardware Description Language)?

A dwarf-killing giant lines up 10 dwarfs from shortest to tallest.The giant randomly puts a white or black hat on each dwarf. No dwarf can see their own hat. The giant will ask each dwarf, starting with the tallest, if they answer incorrectly, then he will kill them.Each dwarf can hear the previous answers, but cannot hear when a dwarf is killed.The dwarves are given an opportunity to collude before the hats are distributed.What strategy should be used to kill the fewest dwarfs?
