Standard VHDL 1076.1.1 Packages for Multiple Energy Domain Support

This paper describes the set of packages providing a standard for the declaration of the most frequently used constants and types required for multiple energy domain modeling. Use of these packages with their defined types, constants and attributes is intended to provide a mechanism for writing VHDL models (compliant with IEEE Std 1076.1-1999) that are portable and interoperable with other VHDL models adhering to this standard. The standard serves a broad class of applications including electronics, thermal, magnetic, optical, fluidic and mechanical systems. The work described is the culmination of efforts by groups with the same basic goals working over a period of over two years. During this time many individuals have made valuable contributions to the development of this standard from the academic, industrial and EDA communities. In this paper, rather than describe every aspect of the standard in detail (impractical in a short paper), we have highlighted the key elements of the proposed standard.
