Derive the logic circuit of a 16-bit adder. (You can use Design Compiler if you know how to use it). Report the netlist of your adder.
2. (40%) Insert BIST circuit into your adder, by using a 7-stage Linear Feedback Shift-Register (LFSR), as the automatic pattern generator of 127 pseudo random patterns, and a Multi-Input ShiftRegister (MISR) as the signature analyzer. Report the netlist of your BISTed circuit, and its golden signature when the circuit is fault free.
3. (10%) Set up the simulation environment to verify if your adder can operate at the speed of 1GHz? Report the execution trace.
4. (40%) Find a procedure to approximate the maximum operating speed of your BISTed adder design. During the procedure, use 100ps as the time resolution when you tune the clock cycle time for the simulation. Report your execution trace and the final conclusion. (Note: The procedure could be either manual or automated by a script.
