幫我用quartus2設計貪吃蛇遊戲，得分用7段顯示器表示用com控制讓兩個7段顯示器都會亮(0是亮1是暗)，8x8led面板為地圖(0是亮1是暗)，不用註解

الفكرة

设计与显示

设计了一个蛇游戏，显示得分在两块7段显示屏上，地图在8x8 LED矩阵上。

选择合适的语言

决定使用Verilog语言，还需实现8x8 LED矩阵控制，两块7段显示屏的COM控制，以及游戏逻辑如蛇的移动、食物放置、碰撞检测和得分。

编写代码

我正在撰写代码，涵盖时钟分频器、7段显示屏驱动器、8x8 LED矩阵驱动器和游戏逻辑。考虑到可能未提及输入，我将自动移动。代码尽量简洁。

编写Verilog代码

我正在为Quartus II编写Verilog代码，实现一个简单的蛇游戏，包括时钟分频器、7段显示屏驱动器、8x8 LED矩阵驱动器和游戏逻辑，确保代码清晰无注释。

Updating the register for two-digit scores

Making scoreboard adjustments

Thought about vector index error 花的時間為 幾秒

الإجابة

下面的程式將 score 宣告成 8 bit，這樣就可以順利使用 score[3:0] 與 score[7:4] 來分別對應到個位數與十位數。請直接使用此程式碼 (無註解)，即可解決先前的 index-out-of-range 錯誤。

只要把原本的 score 從 4 bit 改成 8 bit（如上所示 reg [7:0] score;），並且依照 score[3:0] 對應個位數、score[7:4] 對應十位數即可解決問題。
