Description / Abstract:
This standard defines a collection of VHDL 1076.1 packages,
compatible with IEEE Std 1076.1™, 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.
Purpose
The definitions of IEEE Std 1076.1 allow users to build
simulation models of physical components and subsystems that may
belong to multiple energy domains (electrical, fluidic, mechanical,
etc.). Such models are built upon sets of properties that are
specific to each energy domain and encapsulated in so-called
natures. IEEE Std 1076.1 provides a mechanism to define natures,
but intentionally does not predefine any standard set of natures as
it is expected that this would be done in a subsequent IEEE
standard 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 among vendors.
