The Design of Digital Clock Based on FPGA
Abstract: As the widly use of digital clock, using the chip of EP1C3T144C8N, the design of a digital clock uses the EDA technology and hardware description language VHDL language as the system logic design description method.The digital clock consists of ucontrol module, timing module, data encoding module and display module. In the QuartersII tool software environment, using top-down design ideas, the simulation and debugging of the clock is realized.After experimental verification, the system is able to complete hours, minutes and seconds respectively show and timing function was contraled bye the key input.
Key Words: Digital clock; Hardware description language; VHDL; FPGA
