In the cvs multiple files are available, but there is not mentioned
which one is the top level one. So I don't really know if it is
"controller.vhd" or "atahost.vhd".
[rih] It is atahost.vhd.

In my believe, it should be "atahost.vhd". But there are also ATA
signals available next to the wishbone signals. Do I only need to
handle the wishbone signals and can ignore the ata signals?
[rih] I suppose you want to connect a harddisk? Well at least an ATA device.
If you ignore the ata signals, what are you going to connect it to??

Cheers,

Hello, I'm new to vhdl development, but should like to try to get the ata-3 IP-core working in a little project. ( core: http://www.opencores.org/projects.cgi/web/ata/overview ) But I had some questions about this one. In the cvs multiple files are available, but there is not mentioned which one is the top level one. So I don't really know if it is "controller.vhd" or "atahost.vhd". In my believe, it should be "atahost.vhd". But there are also ATA signals available next to the wishbone signals. Do I only need to handle the wishbone signals and can ignore the ata signals?

Read the docs (pdf) that come with the core. They are quite easy to understand and explain all you need to know about the interfaces (wishbone and ATA). Might I suggest you spend a little more time investigating what you already have at your fingertips?
