Expected questions range from : timing analysis(setup & hold time violations), digital design(most important),digital vlsi design(circuits questions), computer architecture(RISC & CISC), Verilog/VHDL questions.Very large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit chips were widely adopted, enabling complex semiconductor and telecommunication technologies to be developed.
