这个问题说明你在仿真文件里面没有说明仿真时间,也就是说没设置 $finish 语句,这时候iverilog里的vvp进程不会退出。所以说这个gtkwave相当于从vvp进程中打开,自然找不到。

解决办法是手动输入 finish 指令退出vvp进程,再手动输入gtkwave打开指令

另外就是在tb文件中添加 $finish 语句 设置仿真时间让vvp自动退出。

已经解决了,感谢!还有个小问题:运行simulate时怎么可以让.vcd波形文件和.vvp一起生成在prj文件夹下呢?目前只有.vvp在prj下面

vcd文件的创建是iverilog决定的,不是插件决定的,你可以尝试更改tb文件中的 $dumpfile 语句,具体申明创建到哪个路径,建议使用绝对路径,不然插件无法识别。

此外对于标准文件结构的分类,针对prj文件夹下的其实是可再生文件夹,就是说将整个prj文件删除也能在插件中还原出来,只要保证配置相同,这样做的目的一个是方便版本分发,另一个是设计时更加关注设计源文件(src文件夹下的内容)和输出文件(工程根目录下的内容),故不建议将输出文件vcd放置prj下。
