Error (10219): Verilog HDL Continuous Assignment error at led.v(8): object "led" on left-hand side of assignment must have a net type

这个错误意味着在你的Verilog HDL代码中,led的左侧不能是一个普通的变量,而应该是一个网络类型(net type)。网络类型是一种特殊的数据类型,用于表示信号或电路连接。
为了解决这个问题,你需要将led声明为一个网络类型,比如wire或reg。例如,你可以使用以下代码来修复错误:
wire led;
assign led = ~rst_n;
在这个例子中,我们将led声明为一个wire类型,然后使用连续赋值语句assign将其连接到~rst_n信号。请确保在赋值语句中使用正确的网络类型以解决该错误。

Error (10219): Verilog HDL Continuous Assignment error at clock.v(66): object "hour" on left-hand side of assignment must have a net type
This error message is indicating that there is a syntax error in the Verilog code related to a continuous assignment statement. Specifically, the variable "hour" on the left-hand side of the assignment statement is not declared with a proper net type.
In Verilog, variables that are used in continuous assignment statements must be declared with a net type, such as wire or reg. If a variable is not declared with a net type, then the compiler cannot determine how to treat it in the context of the assignment statement.
To resolve this error, you should declare the "hour" variable with the appropriate net type before using it in a continuous assignment statement. For example, you could use the following syntax to declare "hour" as a wire:
wire hour;
Then, you can use "hour" in a continuous assignment statement without encountering the error.
Error (10219): Verilog HDL Continuous Assignment error at test2.v(33): object "q" on left-hand side of assignment must have a net type
Verilog HDL中的Continuous Assignment语句只能用于对端口或者wire类型的信号进行连续赋值,不能用于对reg类型的信号进行赋值。因此,在你的Verilog代码中,当你尝试对一个reg类型的信号进行连续赋值时,就会出现这个错误。要解决这个问题,你需要将q的声明从reg类型改为wire类型:
```verilog
wire [7:0] q;
```
在此之后,你就可以在Continuous Assignment语句中对q进行连续赋值了。
