본문내용

∙ 실습 목적
하나의 7-세그먼트는 한 자리 16진수를 출력할 수 있다. 그러나 FPGA에서 한 자리 16진수는
4비트에 저장되며, 7세그먼트에 출력하기 위해서는 디코딩을 해야 한다. 본 실습에서는 스위
치 입력으로 저장된 0x0~0xF 사이의 한 자리 16진수를 7세그먼트에 출력하기 위한 디코더를
설계한다.
∙ 실습 내용
[그림 3-23]은 DigComV32에서 7-세그먼트의 연결상태를 보여준다.

<중 략>

약 40ns의 딜레이가 생겨 늦게 출력되는 것을 볼 수 있지만 문제되지 않는다.
스위치를 누르면 clk의 전압상승이 일어나면서 동시에 입력 값이 발생하고 그에 따라 디코더
에서 7비트 출력 값이 나와서 7세그먼트에 숫자가 표현된다.
그리고 두 개 이상의 스위치가 ‘1’일 때 출력을 관찰해보면 아무 동작도 하지 않고 이전의 출
력이 그대로 유지되는 것을 볼 수 있다.
(한 개의 스위치가 ‘1’일 때 이외의 값은 null값으로 했기 때문이다.)
