I tried to add my cpld files to the Atom Godil project in ISE but it did not recognise these files. Even when I force an error ( keyword:
entyty ) there was no error. How can I add my two sources?
How exactly did you add the sources?
As well as placing them in the src directory, you need to tell the Xilinx tools about them (with the Add files option) so they get added to the project. At that point they should be visible in ISE.
Then you will need to update the top level design TopRoland.vhd (or create a new one) to instantiate each of CPLD designs:
https://github.com/hoglet67/AtomGodilVi ... Roland.vhd
in the same way it currently instantiates AtomGodilVideo (but probably there will be no Generics).
Then you will been to add all the extra signals to the top level design, and finally to the .ucf file.
Yes, it's a very tedious process.
What you are doing is actually not that common (i.e. merging separate existing designs into one).
