PNR flow and basics of PD
Nothing unexpected they ask only valid questions at least which are required for them
The question was about the placement of flops during routing. The interviewer asked me if there is a wire or an interconnect where exactly would I want to place a flip flop into the design-At the start, in the middle or the end. She gave X, Y locations and wanted me to identify where I would be placing the flops to stabilize the design.
first interview 1) setup hold constrains 2) draw VTC of inverter and explain it, how can you move the curve 3) question about the capacitance of inverter 4) given one priority encoder 4:2 implement 16:4 priority encoder 5)implement Mux 4:2 Second interview 1) draw FF using Mux and get the setup, hold and CQ from the FF design 2)Draw SRAM and explain it functionality 3)question about capacitor Jumps
