Abstract: In this paper, the process of designing multifunctional digital clock by the Verilog HDL top-down design method is presented, which has shown the readability, portability and easily understanding of Verilog HDL as a hard description language. Circuit synthesis and simulation are performed by Altera QuartusⅡ 4.1 and Modelsim SE 6.0. The program can be used in the truly digital clock display by downloading to the FPGA chip.
