Written test: - Questions on C and pointers with different types of Cast - Vhdl questions about sequential and combinatorial circuits - Semiconductor questions and layout of a not in cmos , latches and flops -Fourier and Laplace trasform Orals: -implement the body of the standard C function memcpy and explain why it returns a void* - they gave me a two line of a vhdl program and they asked me what is the difference ( basically they both do the same thing excepts the second does not reset the output in case of wrong condition) - They draw me a waveform of a sequential circuit( clock, input and output) and they asked me to draw the circuit that implement it. The circuit contains two flops and one or two logic gates. - They asked me what is clock gating and prove them why it consume less. - Some questions about MMU and real time OS The interview is really stressing because it last seven hours and every interviewer come one after the other.
