Description: This experiment uses VHDL hardware description language to design a 0 ~ 9999 addition counter. According to a certain frequency of the trigger
Clock, the counter counts up, and the use of digital tube display, when the count to 9999, 0 to re-count.
SW0 is the reset switch. When the switch to the high point of ping, the counter to 0, when the switch to low, the counter began to count.
The circuit includes a frequency dividing circuit, a counter circuit, a binary-to-BCD code circuit and a digital tube display circuit.
