大家好,
这是关于ps2鼠标协议的一个例子。 最高实体: entity mouse_led是 港口 ( clk,reset:in std_logic; ps2d,ps2c:inout std_logic; led:out std_logic_vector(7 downto 0) ); 结束mouse_led; 和我的constratints: 顶部的限制 #CLK声明并连接到C9 50 MHz时钟 NET“clk”PERIOD = 20.0ns HIGH 50%; NET“clk”LOC =“C9”| IOSTANDARD = LVTTL; NET“重置”LOC =“K17”| IOSTANDARD = LVTTL | 拉下; # #PS2 PINS NET“ps2c”LOC“G14”| IOSTANDARD = LVCMOS33 | SLEW = SLOW | DRIVE = 8; NET“ps2d”LOC“G13”| IOSTANDARD = LVCMOS33 | SLEW = SLOW | DRIVE = 8; ##################################### OUTPUTS ############ ################# #LED引脚 # NET“led”LOC =“F9”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“E9”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“D11”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“C11”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“F11”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“E11”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“E12”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; NET“led”LOC =“F12”| IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8; # #文件结束 # 翻译失败: 警告:ConstraintSystem:176 - 在文件中:contraints.ucf(8):语法错误。 确保先前的约束规范以';'终止。 警告:ConstraintSystem:176 - 在文件中:contraints.ucf(9):语法错误。 确保先前的约束规范以';'终止。 为什么? 我不明白。 针脚不在。 这是一个问题吗? 这是我第一次尝试输入引脚。 以上来自于谷歌翻译 以下为原文 Hi all, this is an example on ps2 mouse protocol.
