　　5 Conclusion

　　Here, FPGA is used to form the core control circuit to generate the control signal of the analog waveform, and then the peripheral circuit is used to generate the sawtooth wave and the step wave. Through experimental observation, the generated waveform is clear and has no clutter interference. It shows that the analog circuit can handle the gradual signal well, which fully reflects the advantages of the analog circuit. Moreover, in actual engineering, the sawtooth wave and the step wave are reasonably used to generate various analog waveforms required by the project. As long as some of the circuits are slightly modified, they can be applied to other application systems.
