Pseudo - Cadence Design Platform And Pcb

In this dissertation, the circuit of fake pseudo-noise code fuse is researched, and simulated, evaluated, validated and analyzed with the Cadence software. Upon this basic, the electro-circuit is designed and the PCB board is drawn. The major work of this dissertation contains several points shown below:(1) Research the circuit of fake pseudo-noise code fuze. First of all, research the principle of the circuit of fake pseudo-noise code fuze, and therefore design a circuit of fake pseudo-noise code fuze, and figure out the frame plot of this circuit; Secondly, research the trait of the fake pseudo-noise code, advance a blue print which may generate this kind of code, design the principle frame of the blue print advanced above and carry out the design of the hardware circuit. And then verify whether the code which is generated by the circuit fits the trait of the fake pseudo-noise code or not, analyze its spectrum distribution.(2) Design, simulate and evaluate the circuit of the fake pseudo-noise code fuze. On the basis of the frame above, design the circuit of the fake pseudo-noise code fuze with the Signal Processing System of the Cadence, including the signal sources, filters and other circuits needed. Simulate and evaluate the circuit, examine the signal exported from each module, Analyze the function of the circuit and make any optimization along with the signals from each module, and do these jobs all the time so as to fit the desire.(3) Implement the hardware circuit. After designing, simulating and evaluating the circuit, do analyzing in-depth with the fuze circuit, and design the hardware electro-circuit for each part of the circuit in detail; In the PCB board designing tools of the Cadence, load the electro-circuit to the board designing tools, so to produce the net list file; After researching the desire of the high speed PCB board facture, do the board designing and facture of all the circuit system with the board designing tools of the Cadence.
