verilog 不支持你这样孤立的if(reset)你应该把你的if(reset) begin end放到下面的always里面。而always里面现在的code作为else. 另外应该用<=赋值，而不是=。=是给组合逻辑赋值的，你这里PCOUNT明显是个寄存器 always @（posedge CLK）if(reset)PCOUNT <= 0x00030;else PCOUNT <= NPC;
另一种:延时给rden赋值为1 7、代码仿真编译时y语法报错,不可打印的字符:Syntax error, unexpected non-printable character 排查后发现:Modelsim支持ANSI编码,编辑时使用中文打的空格使用UTF-8编码,该空白字符在ANSI编码看来非打印字符,如下: 需要在notepad++等编辑器的编辑里面选择ANSI编码,找到UTF-8编码格式下的中文...

Since an engineer has asserted that all testable conditions have been included, simulation tools are required to report an error if an unexpected condition is tested. The engineer asserted that all conditions were tested but the assertion failed! A better keyword would have been either full or ...

System verilog - Unexpected behavior with force, The problem is that value is a static variable. When you declare a task in Verilog, unless you specify the task to be automatic, all the variables in the task will be static, meaning each call to the task that modifies a variable does so...
