Error: Can't find name for bus

Hi Guys,

I have a question concerning my Block-Editor-Project, which I have been working on. I have to connect a counter, which has a 20 bit Output to a lmp_compare-Symbol, which has a 20 bit Input.

Somehow Quartus complains while synthesis and gives me the error message:

Can't find name for bus

If I click on the error message it shows the bus line I mentioned above. I always thought that, this bus line didn't need a name. I named the bus also, but that doesn't cure the problem.

Would be really great, if someone of you could give me a useful hint.

Thanks a lot!

Regards

    Hi,

    as far as I know you have to assign a name to the bus in your schematic.

    Select the bus, right mouse click, choose properties and add a name like a[3..0].

    Kind regards

    Hi,

    Sorry for bothering you. I found the mistake. Guess, I was a bit tired yesterday, when i didn't see that I assigned two different names to the same busline.

    Have a nice day!
