scope:

This standard defines a collection of VHDL 1076.1 packages, compatible with IEEE Std 1076.1™-1999,1, 2 along with recommendations for conforming use, in order to facilitate the interchange of simulation models of physical components and subsystems. The packages include the definition of standard types, subtypes, natures, and constants for modeling in multiple energy domains (electrical, fluidic, mechanical, etc.)

The packages are intended for use primarily in the modeling of multiple energy domain systems. The range of operation of the packages is not defined in this standard, but is intended to be valid across a wide range of disciplines and applications.

This standard is embodied in the package declarations for the following packages:

- FUNDAMENTAL_CONSTANTS

- MATERIAL_CONSTANTS

- ENERGY_SYSTEMS

- ELECTRICAL_SYSTEMS

- MECHANICAL_SYSTEMS

- RADIANT_SYSTEMS

- THERMAL_SYSTEMS

- FLUIDIC_SYSTEMS
