    hi,

    i'm planing a decrementer that subtract 1 from a 'N' bits number's .
    but the planing is to do it in NCL - Asynchronous logic.
    i have some errors and i can't resolve it.
    here is the vhd source

    http://www.upf.co.il/file/792430098.html

    here is the errors:

    (vcom-1348) Prefix (label "carry") of indexed name is not an array.

    (vcom-1348) Prefix (label "carry") of indexed name is not an array.

    Indexed name is type (error); expecting type work.ncl_pkg.ncl_bits.
    (vcom-1454) Formal "c_or" of mode OUT cannot be associated with an expression.

    Hi,

    The problem is at line 183 :

    carry : entity work.or_xnor_ncl

    because carry is already the name of one of your signals, then you have to rename it.
