most complicated block i have ever done in apple
you have 2 types of balls, red and white, you have 3 boxes 1 with red balls, 1 with white balls, 1 combined. the boxes are labeled with stickers. the stickers are not correct! one box marked as "red" second box is marked as "white" third box is marked as "combined". how many tries you need to know which box is realy the red,white and combine.
Basics, everyone is interested to know depth of your knowledge so for graduates they will start from CMOS transistor level and keep going higher to SoC design level. As along as you could break, its ok to say if you don't know about something, they are interested to see where you got broke and measure depth of your knowledge. One advice to all graduates keep your fundamentals clear, that brings confidence and vlsi industry respects people who have knowledge.
when Capacitors in series or parallel what happens to charge and voltage
What did you do on your project
Given a sequential Circuit with delays and asked about the frequency and slack of the circuit..?
the interviewer gave me scheme of two blocks, in the left block (block A) there were 2 FF, FFa and FFb. in block B there were only logic. FFa routed through logic to block B, and returned through logic to FFb in Block A. the interviewer tell me that is 150ns delay in the timing path between FFa and FFb, and ask me to describe what can be the cause and how to fix it.
