Greetings All:
Continually I create VHDL FPGA projects as required. In the projects, I create several .vhd files, some are specific for that project, some can be used in pretty much any project later, however sometimes they get some modification.
For instance, I created a clock_generator.vhd for dividing the main clock to produce a slower clock. That has been used in many other projects. Of course in some projects, the simple clock divider wasn't exactly what I needed, so modified it. I added 'clock enable' ports in and out, changed generics from 'divide_by' to 'clock_in_rate' and 'clock_out_rate' using 'real' type, and a few other things as time progressed.
Now if I start another project, with more than 1 version available it gets difficult to find/copy/paste the file into another project. Bug-fixing is not applicable to other copies as well. At one time I received an interesting suggestion...
http://www.alteraforum.com/forum/showthread.php?t=48216&highlight=#4 I completely agree with the suggestion, it sounds way better than the 'trying-to-find-the-best-most-up-to-date-clock_generate.vhd-file' I'm doing currently. And the 'versioned' part is required because if I have to recompile an old project that uses the first version, it may not be that compatible with the '47th' version I have now. So it still needs to be referenced to that particular reversion file (unless purposefully updating that as well).
Is there any information on file organization, I haven't heard any reference to that regarding to VHDL.

Download svn(Tortoise svn). It is industry's de facto version control software. It is free but meant for servers.You can also use it on your pc without server.
