The definition of IEEE Std. 1076.1-1999 allows one to build simulation models of physical components and subsystems that may belong to multiple domains (electronic, fluidic, mechanical, etc.). Such models are built upon sets of properties that are specific to each domain and encapsulated in so-called natures. IEEE Std. 1076.1-1999 provides a mechanism to define natures but does intentionally not predefine any standard set of natures as it has been expected that this would be done in a subsequent project. The definition of a standard set of natures is crucial to make possible the reuse and exchange of models written in VHDL 1076.1 within and between vendors.

The Working Group will define a collection of VHDL Std 1076.1 packages compatible with IEEE Std. 1076.1-1999, along with recommendations for conforming use, in order to facilitate the interchange of simulation models of physical components and subsystems. The proposed packages will include the definition of standard types, subtypes, natures and constants for modeling in multiple domains (electronic, fluidic, mechanical, etc.)

The Working Group is yet to be formally created under the auspices of the IEEE. A Project Authorization Request (PAR) is currently being submitted to IEEE DASC for approval. It is expected to get the IEEE approval and the IEEE PAR number before the end of year 2001.
