The digital electronic ignition device was composed of 5 sections of MCU control circuit, digital circuit, light emitting diode display circuit, detection circuit and launching circuit.

The paper introduces the design of digital clock based on FPGA and VHDL, the time of clock can be displayed with the digital driving circuit.

The design also joined the commonly used digital control and status lights that indicate lights commonly used circuit, making the whole more complete and more humane.
