关于Vivado non-project模式

vivado有project模式和non-project模式，project模式就是我们常用的方式，在vivado里面新建工程，通过GUI界面去操作；non-project模式就是纯粹通过tcl来指定vivado的流程、参数。

相比于project模式，non-project模式的优势如下：

总结下来就是，不仅节省空间，还更加灵活。

下面我们以vivado中自带的wavegen工程为例：

为了更加快捷的完成non-project的tcl内容，我们可以先把wavegen工程进行Synthsis和Implementation，在wavegen.runs下面会生成synth_1和impl_1的两个目录，这两个目录都有wavegen.tcl，我们可以直接将里面的有用内容copy出来，用来创建non-project的tcl，具体操作就不展开细讲了，直接把最终的tcl文件展示出来，就很很容易理解了：

对于综合时间上，理论上non-project模式要比project模式快一些，因为project模式会把每一步的结果都写入到磁盘中，但non-project中，我们只需要把我们想需要的文件存下来。

在上面的脚本中，也基本上把每一步的结果都存了下来，而且本身Synthsis和Implement的时间也不到2分钟，所以跟project模式的时间并没有明显差别。
