Method for implementing electronic circuit designs that are adaptable to different binary data formats. Separate packages are provided for the different binary data formats. The names of the constants and subtypes are identical as between the packages, and the values associated with the constants and subtypes in each of the packages are particular to the associated data format. A selected one of the packages is imported into the. design, and selected references in the design to binary data are made using the names of the constants and subtypes set forth in the packages. The circuit design is then implemented by synthesizing and mapping the design to the selected device.
