This standard defines standard practices for synthesizing binary digital electronic circuits from VHDL source code. It includes the following: a) The hardware interpretation of values belonging to the BIT and BOOLEAN types deÞned by IEEE Std 1076-1993 and to the STD_ULOGIC type defined by IEEE Std 1164-1993. b) A function (STD_MATCH) that provides "don't care" or "wild card" testing of values based on the STD_ULOGIC type. c) Standard functions for representing sensitivity to the edge of a… read more signal. d) Two packages that deÞne vector types for representing signed and unsigned arithmetic values, and that define arithmetic, shift, and type conversion operations on those types. This standard is designed for use with IEEE Std 1076-1993. Modifications that may be made to the packages for use with the previous edition, IEEE Std 1076-1987, are described in 7.2. read less

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.
