[0.3.3]RuntimeError: null function or function signature mismatch

mathsmatics commented 7 months ago

U7C}9VP Z5719IV6_@@L8KS 复制源代码进文件夹之后，然后把文件夹拖到vscode，然后显示是否生成json文件，点的是，然后点文件的时候就会报这个错，然后报错的文件，就无法进行变量关联

就是写代码的时候，定义过的变量不能自动补全，感觉问题出现的原因和这个报错有关

我尝试所有文件新建文件，再粘贴内容的，粘贴下面这段的时候，报错： Errors happen when parsing d:/projectFile/ModelSim/OpenMIPS/rtl/ex_mem.v. Error: "RuntimeError: null function or function signature mismatch". Just propose a valuable issue in our github repo 😊
