IV及以前的FPGA器件，如Cyclone III芯片器件等，但此版本已停止更新。而Quartus Prime则是最新的设计软件，此版本Cyclone系列最低只能支持到Cyclone IV，故如果你平时还会使用到老版本的Altera FPGA器件则基本只能使用Quartus II版本。此外，除了支持的FPGA器件不同外，软件界面及使用上延续性较好，两个版本使用起来差别不大。另外一个需要注意的就是Quartus Prime有精简版（Quartus Prime Lite Edition），此版本可以免费试用。 如果使用Quartus II，则13.0和13.1版本都可以。不同版本项目打开时可能会提示你需要自动转换项目版本。 Ancient people did not discuss it.
