# VIVADO開發流程(TCL)

本篇目標建立一個tcl mode工作流程

## A. Project mode

project mode主要目的是建立一個script，再做synth,imp都直接在terminal上跑，但看訊息還是到gui做

### A-1. tcl Sample code

以下範例是在建構好一個vivado project之後，在裡面建立一個tcl script(例如: project\_build.tcl)並依照剛剛建立的vivado  project名稱修改tcl內容

```tcl
set current_dir [pwd]
#puts "Print current_dir: $current_dir"

set project_name "your_project.xpr"
#puts "Print project_name: $your_project"

set project_path [file join $current_dir $project_name]
#puts "Print project_path: $project_path"

open_project $project_path
#open_bd_design {<project path>/sources_1/bd/design_1/design_1.bd}
#validate_bd_design
update_compile_order -fileset sources_1

reset_run synth_1
reset_run impl_1
#reset_run impl_1 -prev_step 

launch_runs synth_1 -jobs 7

wait_on_run synth_1

#launch_runs impl_1 -to_step write_bitstream -jobs 7
launch_runs impl_1 -jobs 7
wait_on_run impl_1

launch_runs write_bitstream -jobs 7
wait_on_run write_bitstream 
#launch_runs impl_1 -to_step write_bitstream -jobs 7
```

執行的時候在linux端進到vivado project folder內部執行以下命令

```sh
vivado -mode batch -source project_build.tcl
```

也可以使用>>把執行的訊息導到某個log/txt內，寫法如下:

```bash
vivado -mode batch -source RCCB_Scan_Ctrl.tcl >> aa.txt 
```

### A-2. import tcl

如果今天上網抓一個project下來用，通常都會是tcl srcipt，因此要使用tcl srcipt mode:

1. 開啟vivado gui
2. cd 你git clone或下載下來的檔案位置
3. 使用vivado gui上的"run tcl srcipt"

## Note:

* 想要在tcl執行時[有顏色](https://wiki.tcl-lang.org/page/ANSI+color+control)，再找時間研究
