出现Error (10500): VHDL syntax error at msk.vhd(23) near text "!"; expecting "then"怎么修改

这个错误提示表明在你的 VHDL 代码的第 23 行附近存在语法错误,可能是因为你在一个条件语句中使用了错误的语法。请检查你的代码,确保你的条件语句中包含了正确的关键字和语法结构,例如:
```
if (condition) then
-- do something
elsif (condition2) then
-- do something else
else
-- do something different
end if;
```
另外,注意在 VHDL 中,逻辑非运算符是 "not" 而不是 "!"。如果你在条件语句中使用了逻辑非运算符,请将其替换为 "not"。

Error (10500): VHDL syntax error at mux81.vhd(18) near text "end"; expecting ";"
在 VHDL 的语法中,当你使用 if-then-else 语句时,需要使用 end if; 来结束语句。你的错误提示指出在 mux81.vhd 的第18行出现了错误,可能是因为你忘记添加分号或者没有正确地结束语句。
请检查第18行的代码,并确保在 if-then-else 语句的末尾添加了 end if;。例如:
if (sel = '0') then
out <= in0;
else
out <= in1;
end if;
Error (10500): VHDL syntax error at ex1.vhd(5) near text ¼
As an AI language model, I cannot see your code. However, in general, this error message indicates that there is a syntax error in your VHDL code. The error is occurring near the text "¼," which may indicate that there is an illegal character or an incorrect symbol being used in your code. Double-check your code for any typos, incorrect symbols, or illegal characters, and make sure that everything is properly formatted and aligned. If you are still having trouble, consider seeking help from a VHDL expert or reference guide.
