First,the content and demands of experiment is presented in the essay,the design principle of multi-function digital clock is also introduced.The method of module integration after designing and simulating each module is taken to implement the experiment.After packaging all module,all the modules are integrated to realize the final electric circuits,implementing all the demands of multi-function digital clock design. Second,the method and steps of the experiment is presented.Using programmable logic devices,the electric circuits are designed in software QuartusII to realize the multi-function,which is called FPGA. Firstly, the frequency dividing circuit is designed to get the frequency required by dividing the frequency of 48MHZ from the experiment box.Then,the timing circuit and decoding-and-display circuit are also designed,which are all simulated in software to test their validity.After all,the time adjustment circuit,the time maintain circuit,the time cleared circuit and the alarm circuit are also designed,which are simulated in the software to test their correctness.After packaging all the circuits into modules,the modules are integrated to finish the multi-function digital clock design. Last,the final circuit is downloaded to the SmartSOPC experiment system to test its validity after assigning all the pins of the final circuits.
