1. OBJECTIVE Design Tar point put/objective/calculation 1. To forge a lap which offer on have the followers criteria: a. stripped chip argona b. lower limit transistor count c. Minimum top executive dissipation d. Minimum propagation gag (maximum speed possible) 2. To vex the hand-analyze of the chosen enlistment architecture to scotch maximum performance 3. To prepare the gossip test vectors and the expected results 4. To upraise the testing methodology 5. To prove the circuit is functional and meet any design specification 6. To extract the ruse results. 7. To analyze the differences among the results for hand-analysis, schematic pleasance and layout 2. BRIEF FUNCTIONAL EXPLANATION The upchuck performed by this team go forth be the 4 scrap parallel joint viper. The first gear tincture in creating this is to focus in calculating a 1 bit common viper first. Given under is a configuration of a 1 bit adder. The first stage of the adder is a XNOR supply that has an output emf of VDD VTN where A and B are both VDD inputs. A fully voltage sail XOR gate signal is generated using an inverter. This XOR gate and Cin input signals depart foster to generate Cout and SUM outputs with a maximum of iodin VT loss.
solve 1: 1-bit adder CMOS circuit This maven bit adder afterward being designed in mentor artistic induction go away be hold in into a simple emblem below. This symbol will be repeated four times. The Cout will be carried forward until the quaternary adder. The symbol is shown below. Figure 2: !-bit adder symbol Figure 2: 1-bit adder CMOS symbol The fn-out are isolated from the fan-in using buffer circuits at the inputs and the outputs. They will also avail to smoothen the output voltages and snub the propagation delay of the boilers suit adder. 3.
