    Top
    I would be happy to share, but at this point I do not have a place to
    upload to unless space can be provided on the opencores site. I do not
    consider the project suitable for uploading to cvs because I have not been
    able to maintain a clean separation of various parts of the design. By this
    I mean I have not been able to separate into different directories the
    sdram controller, terminal, or1k, etc because of WebPack's inability to
    keep things separated and still have the build and simulations work.

    If a place can be provided where I can put the files for others to access,
    I will be happy to share.
