🔹 測試資料

🔹 題目

未使用的規定接角每隻扣10分

qustion

🔹 規範

KiCad 圖框

未完成每項扣10分

Title: [術科測試編號(8碼)]-[崗位編號]
Date: 測試日期

資料夾

未完成每項扣10分

要求在 D:\ 放置兩資料夾

[崗位編號]_CPLD : KiCad 專案
[崗位編號]_Layout : Quartus 專案

(建議)
(假設工作崗位為 01)

D:
├── 01_CPLD
│   └── cpld      : Quartus 專案
└── 01_Layout
    ├── layout    : KiCad 專案
    ├── sch_f.pdf : 正面佈線圖
    └── sch_b.pdf : 背面佈線圖

由於專案名稱不能以數字開頭
所以完成後再將整個專案複製進資料夾

🔹 流程

	內容	描述	建議花費時間
一	檢查材料
二	KiCad	1. 原理圖 2. 佈線圖 3. 列印	< 1 hr
三	焊接	1. 子板 2. 母板	< 2.5 hr
四	Quartus	1. verilog 2. 腳位配置 3. 燒入	< 0.5 hr
五	評分

🔸 試題一、四位數顯示

CPLD

共陰極七段顯示:
對於 output reg[6:0] seg

1 = ON
0 = OFF

module cpld(
    input clk,
    output reg[3:0] scan
    output reg[7:0] seg
);

reg[11:0] div;
always @(posedge clk) begin
    div <= div + 1'b1;
end

always @(posedge div[11]) begin
    case(scan)
        4'b0001: begin scan <= 4'b0010; seg <= 8'b11111111; end // 8
        4'b0010: begin scan <= 4'b0100; seg <= 8'b11111111; end // 8
        4'b0100: begin scan <= 4'b1000; seg <= 8'b11111111; end // 8
