vivado有project模式和non-project模式，project模式就是我們常用的方式，在vivado里面新建工程，通過GUI界面去操作；non-project模式就是純粹通過tcl來指定vivado的流程、參數(shù)。

相比于project模式，non-project模式的優(yōu)勢如下：

總結(jié)下來就是，不僅節(jié)省空間，還更加靈活。

下面我們以vivado中自帶的wavegen工程為例：

為了更加快捷的完成non-project的tcl內(nèi)容，我們可以先把wavegen工程進行Synthsis和Implementation，在wavegen.runs下面會生成synth_1和impl_1的兩個目錄，這兩個目錄都有wavegen.tcl，我們可以直接將里面的有用內(nèi)容copy出來，用來創(chuàng)建non-project的tcl，具體操作就不展開細講了，直接把最終的tcl文件展示出來，就很很容易理解了：

對于綜合時間上，理論上non-project模式要比project模式快一些，因為project模式會把每一步的結(jié)果都寫入到磁盤中，但non-project中，我們只需要把我們想需要的文件存下來。

在上面的腳本中，也基本上把每一步的結(jié)果都存了下來，而且本身Synthsis和Implement的時間也不到2分鐘，所以跟project模式的時間并沒有明顯差別。
