这个错误提示是因为 always 前面缺少了一个语句块的括号,应该在 always 后面添加一个 begin/end 语句块,像这样:
```verilog
always @(posedge clk) begin
if (rst) begin
seg = 4'b0000;
end
end
```
这样就可以消除这个错误了。

always @ (posedge clk or posedge rst) begin if (rst) begin seg = 4'b0000; end else Error (10170): Verilog HDL syntax error at keshe11.v(84) near text "always"; expecting ";", or "@", or "end", or an identifier ("always" is a reserved keyword ), or a system task, or "{", or a sequential statement这个错误怎么改
这个错误是因为 always 语句中的语法有问题。你需要在 always 后面添加 @(*) 或者 @ (posedge clk) 来指定触发条件。
例如:
```
always @(*) begin
if (rst) begin
seg = 4'b0000;
end else begin
// your code here
end
end
```
或者
```
always @(posedge clk) begin
if (rst) begin
seg = 4'b0000;
end else begin
// your code here
end
end
```
注意:以上代码只是示例,你需要将其中的代码替换成你自己的代码。同时,还需要确保你的代码没有其他的语法错误。
always @ (posedge clk or posedge rst) begin if (rst) begin password = 4'b0000; inputnum = 4'b0000; display = 4'b0000; deletenum = 4'b0000; deletecount = 2'b00; inputcount = 2'b00; displaycount = 2'b00; i = 2'b00; lock = 1'b0; end else begin // 输入数字 if (sw != 10'b11111 sw != 10'b1111111111) begin inputnum = sw[3:0]; // 如果已输入4位数字,则不再接受输入 if (inputcount == 2'b11) begin inputnum = 4'b0000; end Error (10170): Verilog HDL syntax error at keshe11.v(42) near text "sw"; expecting ")", or "?", or binary operator这个错误怎么改
这个错误提示是因为你在 if 语句中的逻辑表达式中使用了两次 "sw" 变量,但是中间没有逻辑运算符将它们连接起来。你需要使用逻辑运算符 "&" 或 "|" 将它们连接起来。
你可以将 if 语句中的逻辑表达式改为:
```
if ((sw != 10'b11111) & (sw != 10'b1111111111)) begin
```
或者
```
if ((sw != 10'b11111) | (sw != 10'b1111111111)) begin
```
这样就可以避免这个错误了。
