Should not require the (dummy) VHDL body of foreign functions.
Can not require the definition of foreign functions, unless actually used.
Calling convention
Keyword IMPORT_C or VFFI.
Allow multiple registrations for different tools.
Deferred definition of external subprograms
Allow
prototype
?
Name mangling ?
Interface modes and classes
in, out, inout
constant, variable, signal
support wait ?
Types
fat pointer for unconstrained arrays
fat pointer for accesses to unconstrained arrays
Note: in GHDL fields data and bounds/range are in a different order within the struct. That's because of slices.
Memory layout
to vs downto
bit ordering within bytes: reverseBitsInBytes
vfficharArr2bitArr, vffibitArr2charArr
multidimensional arrays
