self-made tool for risc-v development

Another self-made tool for risc-v development, it is a vcd file dumper. With our own dumper, we can record the behavior of another risc-v, so we can cross check our risc-v correctless much more efficient.

logic gate呢一層

我地平時用嘅variable,如果化到落logic gate呢一層,你無法找到佢嘅真身,佢亦都好可能同其它variable所化生嘅logic gate交織埋一齊,你亦都無可能找到佢確實嘅存在嘅時間,一切好虛無,但有其功用。呢個係coding體驗空性嘅其中一個睇法。而家啲programmer執著玩排位玩放位玩lang玩framework,真係好可憐。

6 hours to fix my antlr netbeans plugin
