[Quartus v14.1] Top-level entity name

Hi all,

I've a project that was made under Quartus II v12 that I've opened in v14.1.

The top-level entity is a .bdf file with name containing a dash "XXXXX-XXXX.bdf".

It wasn't possible to me to let it be the top-level entity until I've replace the dash with an underscore "XXXXX_XXXX.bdf", re-opened the project and set it as top-level entity with no problems.

Is it really the problem regarding the dash? Why it did works with v12 and no more yet?

Thanks in advance,

JGiampiccolo

    The - isn't supported in Verilog and I believe it's not supported in VHDL. This may have been made just to keep them together. (For example, if you simulate the design, which requires writing out a .vo or .vho, it won't be compliant with the standard.)

    That doesn't help, but just a guess as to why...

    Hi Rysc,

    Thanks for your reply, maybe that's the point however it seems to work with Altera 12.x...
