Foreign Interfaces

VHDL provides for some use of foreign languages (e.g. C, Fortran, ADA, etc.)
- Subprogram or architecture body can have non-VHDL implementation
- Designer has access to previously written code or code difficult to write in VHDL
The use of foreign code is mainly implementation dependent
Foreign variables, signals, or entities are not possible
