Including files in Quartus II 14.x Project without compiling

If File2.sv is included in the Project tree, then it will be compiled when File1.sv is compiled (because File1.sv includes File2.sv) and then it will also be individually compiled again as File2.sv by itself which will fail.

I am trying to break down a big module into 2 files for easier navigation. In my case, my module has 2 state machines. To make it easier to work on, I have one state machine inside File2.sv and the other inside File1.sv (they are not really called File1 and Files - these are just example names).

At the moment, File2.sv is not part of my Project tree (even though it is in the same file folder/directory) and it compiles fine as part of File1.sv

I would like it to also appear on the Project tree so I can easily open it if I want to.

Having said this, I have started to use Notepad++ lately for both Modelsim and Quartus since it provides time-saving features a software developer expects such as keyboard macros.

@ShyanYewT_Intel​ I'm used to using IDEs such as MS Visual Studio and even ancient editors such as Emacs. They have "keyboard macros" which allow you to record a sequence of keystrokes and play them back. (Ctrl-Shift-R to start/stop recording and Ctrl-Shift-P to playback recording). Imagine you have a load of port/variable defiintions nicely vertically aligned and you want to move the second columns of words over by 3 characters. You could do this by frantically pressing the space 3 times, moving left 3 times and then moving down one line and doing it all over again. With keyboard macros you just record the sequence and playback - so you can hold Ctrl-Shift down and press P for 10 times for 10 lines of change. And keyboard macros can also playback copy and pasting actions too.

Another simple thing I miss in both Quartus/Modelsim editors is the abilty to highlight a black and press Tab (or Shift-Tab) to move the entire block of lines a tab to the right or left. I'm so used to using this that I highilght a block of text in Quartus/Modelsim, press Tab and accidentally delete/replace the highlighted code with a tab character. :-)

Something I haven't tried is whether or not Quartus would allow me to include a file with an unknown extension. For example, it would be useful to be able to includes .txt or .doc files in the Project tree - these would be related files but not files you would want to compile. I could do something silly such as renaming my Files2.sv to File2.paulsv and then tell Notepad++ that a .paulsv file should be syntax highlighted the same as Verilog file.
