本标准定义了与IEEE Std 1076.1（TM）兼容的VHDL 1076.1软件包集合，以及一致性使用建议，以促进物理组件和子系统仿真模型的交换。这些软件包包括多个能量域（电、流体、机械等）建模的标准类型、子类型、性质和常数的定义。这些软件包主要用于多个能量域系统的建模。 本标准中未定义软件包的操作范围，但旨在适用于各种学科和应用。

This standard defines a collection of VHDL 1076.1 packages, compatible with IEEE Std 1076.1(TM),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.
