上面這些文件可以分爲五類：
1. 編譯必需的文件：設計文件（.gdf、.bdf、EDIF輸入文件、.tdf、verilog設計文件、.vqm、.vt、VHDL設計文件、. vht）、存儲器初始化文件（.mif、.rif、.hex）、配置文件（.qsf、.tcl）、工程文件（.qpf）。
2. 編譯過程中生成的中間文件（.eqn文件和db目錄下的所有文件）
3. 編譯結束後生成的報告文件（.rpt、.qsmg等）
4. 根據個人使用習慣生成的界面配置文件（.qws等）
5. 編程文件（.sof、.pof、.ttf等）
上面分類中的第一類文件是一定要保留的；第二類文件在編譯過程中會根據第一類文件生成，不需要保留；第三類文件會根據第一類文件的改變而變化，反映了編譯後的結果，可以視需要保留；第四類文件保存了個人使用偏好，也可以視需要保留；第五類文件是編譯的結果，一定要保留。
在使用版本控制工具時，我通常保留第一類、第三類和第五類文件。但是第三類文件通常很少被反覆使用。
所以，爲了維護一個最小工程，第一類和第五類文件是一定要保留的。
此外，當一個項目的設置內容需要轉移給另一個項目時，例如引腳分配信息，需要轉移.tcl文件而不是.qsf文件。.tcl文件與.qsf文件的關係以及如何生成.tcl文件我會在以後的日誌中給出。
Source files (always under source control)
*.bdf Schematic
*.bsf Symbols
*.inc AHDL include
*.lai Logic analyzer interface
*.mif Memory init
*.ptf SOPC file (old but recommended)
*.qip MegaWizard IP
*.sopc SOPC file
*.tcl Scripts
*.tdf AHDL source
*.v Verilog source
*.vhd VHDL source
*.vwf Simulation stimuli
Assignments & settings (always under source control)
Name.cdf Programming chain settings編程設置文件
Name.qdf Default assignments自動更新，保存全局assignments。
Name.qpf Project file
Name.qsf Assignments (except timing)自動更新，也可以作爲導入文件，但是文件名不要一樣。
Name.sdc Timing constrains. This file should never be written directly by TimeQuest, since it might get randomly rearranged. Write to a separate file and copy-paste into main file.
Name.srf Message supressions
Output files (normally under source control)
NOTE: Do not generate rbf or ttf files unless they are used
Name.pof Programming file
Name.rbf Programming file (normally not present)
Name.sof Programming file
Name.ttf Output in text format (normally not present)
Special cases (consider source control)
\db\*.* Improves quartus compilation time. Lots of files. If and only if incremental compilation will be used this should be under source control.
\simulation\*.* This folder is for ModelSim. Quartus Simulator works without this folder. If ModelSim is used this should be under source control.
Report files (normally not under source control)
*.done Date
*.qarlog Log of project archiving
*.rpt Reports
*.summary Report summaries
Generated files (never under source control)
\timing\*.* No settings, just generated timing stuff
Name.qws GUI settings (window positions is a user rather than project option)
*.cmp Component declarations
*.dpf -幾乎不變，爲一個xml文件，當assignment pins時就會產生
*.eqn Equations
*.html -
*.jpg Images generated by some megawizards?
*.pin -
*.ppf -
Backup files (never under source control)
*.bak Backup of single files
*.qar Quartus archive
