进行多次编译并在每次编译期间更改不同的设置时，可能很难记住每次编译时的设置和结果是什么。可以通过项目存档保留项目的完整副本，包括编译期间生成的文件。可以在系统命令提示符下使用单个命令对项目进行存档，但创建 Tcl 脚本并添加自动执行此脚本的设置可简化这个过程。
要使脚本在每次编译结束时自动运行，请使用以下脚本，并在项目中添加新的赋值。赋值名称为 POST_FLOW_SCRIPT_FILE。有关此赋值的更多信息，请参阅脚本自动执行示例。假设脚本名为 autoqar.tcl，请在 Quartus II 设置文件 (.qsf) 中添加以下赋值：
set_global_assignment -name POST_FLOW_SCRIPT_FILE quartus_sh:autoqar.tcl
此脚本根据当前日期和时间创建一个文件名。有关更改日期和时间表示格式的信息，请参阅“日期和时间格式化”页面。
