Error (12007): Top-level design entity "ly" is undefined

这个错误通常是由于没有正确定义顶层实体引起的。请检查您的代码,确保您在顶层实体中正确地声明了"ly"。
例如,如果您的代码应该是一个VHDL文件,则应该包含以下内容:
```
entity ly is
port (
-- 输入输出端口声明
);
end ly;
architecture Behavioral of ly is
-- 实现代码
begin
-- 实现代码
end Behavioral;
```
请注意,实体名称和文件名必须匹配,并且实体声明必须出现在实现代码之前。 如果您使用的是Verilog语言,请使用类似的语法来定义您的顶层实体。

Error (12007): Top-level design entity is undefined
这个错误通常表示你的设计文件中没有定义顶层实体。在设计文件中,你需要定义一个顶层实体,它是你的设计的入口点,它应该包含所有你的设计模块的实例化。你需要检查你的设计文件,确保它包含一个顶层实体,并且该实体的名称与你的顶层模块的名称相同。如果你已经定义了顶层实体,并且名称也正确,那么你需要检查你的设计文件是否正确引用了所有必需的模块。
Error (12007): Top-level design entity "jishu" is undefined
This error indicates that the top-level design entity named "jishu" has not been defined or declared in the Verilog code. The compiler cannot recognize the module or entity named "jishu" and hence cannot proceed with the synthesis process.
To resolve this error, you need to make sure that the top-level design entity is properly defined and declared in your Verilog code. Check the module declaration and make sure that the module name matches with the top-level entity name. Also, check if all the required inputs and outputs are defined and declared properly.
Make sure that you have not misspelled the name of the module or entity. Also, make sure that the Verilog file containing the top-level entity is included in the project or compilation unit.
Once you have made the necessary corrections, try recompiling the code to see if the error has been resolved.
