Application background Don't download the program by using VHDL language to design multifunctional multi-function digital clock, the design has, and seconds display function, the school and the whole point timekeeping function; system clock source module, frequency module, timing module, timing module, digital tube display module and the whole point timekeeping module composition; in the Quartus II environment comprehensive compilation of each basic module and the top principle diagram, after debugging and running, the waveform simulation, the initial realization of the design goal, the programmable logic device FPGA verification, the system can accomplish, and second, the whole point timekeeping function and a button control digital clock reset, school functions. Key Technology (1) establish a design project folder(2) edit the VHDL source file or principle diagram and save it.(3) new project, add the design document, select the target chip, etc.
