Abstract:
A method and system are provided for automatically creating an implicit literal value in a user defined enumerated data type by inserting an additional literal value, scanning the HDL design files for broken interdependencies or potential incompatibilities with the implicitly defined literal value, and modifying the HDL design files to be in accordance with the implicitly defined literal value while maintaining the semantics of the VHDL language reference model.
