上面这些文件可以分为五类：
1. 编译必需的文件：设计文件（.gdf、.bdf、EDIF输入文件、.tdf、verilog设计文件、.vqm、.vt、VHDL设计文件、. vht）、存储器初始化文件（.mif、.rif、.hex）、配置文件（.qsf、.tcl）、工程文件（.qpf）。
2. 编译过程中生成的中间文件（.eqn文件和db目录下的所有文件）
3. 编译结束后生成的报告文件（.rpt、.qsmg等）
4. 根据个人使用习惯生成的界面配置文件（.qws等）
5. 编程文件（.sof、.pof、.ttf等）
上面分类中的第一类文件是一定要保留的；第二类文件在编译过程中会根据第一类文件生成，不需要保留；第三类文件会根据第一类文件的改变而变化，反映了编译后的结果，可以视需要保留；第四类文件保存了个人使用偏好，也可以视需要保留；第五类文件是编译的结果，一定要保留。
在使用版本控制工具时，我通常保留第一类、第三类和第五类文件。但是第三类文件通常很少被反复使用。
所以，为了维护一个最小工程，第一类和第五类文件是一定要保留的。
此外，当一个项目的设置内容需要转移给另一个项目时，例如引脚分配信息，需要转移.tcl文件而不是.qsf文件。.tcl文件与.qsf文件的关系以及如何生成.tcl文件我会在以后的日志中给出。
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编程设置文件
Name.qdf Default assignments自动更新，保存全局assignments。
Name.qpf Project file
Name.qsf Assignments (except timing)自动更新，也可以作为导入文件，但是文件名不要一样。
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 -几乎不变，为一个xml文件，当assignment pins时就会产生
*.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
