  其实github上能够找到不少读取vcd波形的工程，但很多都是快十年前的老工程的，跑起来多多少少有点问题，经过一波测试，终于找到一个比较靠谱的，链接在这里，感谢代码作者的奉献，cirosantilli/vcdvcd。为了便于使用，我对代码稍作了一点改造，放在这个仓库。

  Actually, on GitHub you can find several VCD waveform reader projects. but most are almost 10 years old, and have some problems when running. After a wave of testing, I finally found one that works reasonably, here is a link to it, thanks to the dedication of the author.
