The Standard package is part of the VHDL standard. This package contains definitions for basic types, subtypes, and functions, and the operators available for each of the (sub)types defined. 标准是隐式使用的，不需要用use子句来特别声明。

In the VHDL language, the libraries STD and WORK are implicitly declared in the source code. User programs do not need to declare these two libraries. Library STD contains the standard packages with VHDL distribution. The WORK library refers to the current working directory. There are other libraries that comes with your tool.
In the VHDL code, the full adder is implemented in line 24 on the registered input. Pay attention that before performing the addition operation you must extend the number of bit of the input operand. This is implemented using the standard “ resize ” function provided in the “ numeric_std ” package … 2016-06-27 In the VHDL language, the libraries STD and WORK are implicitly declared in the source code. User programs do not need to declare these two libraries. Library STD contains the standard packages with VHDL distribution. The WORK library refers to the current working directory.
The teaching package is completed with lecture slides, labs and a solutions manual for instructors.

Details are described here. 4. Perform write/read operations. Read/write processes are always performed VHDL is a strongly typed language.
A single package can be shared across many VHDL designs. Uses of Packages: 1) To keep user defined functions and procedures in a common place:

2014-09-27 · The VHDL Programming Interface 1076-2007c is a relatively new standard which defines a C interface to VHDL. The standard is complex and allows manipulation of the simulation process, static data, and dynamic data. From the point of view of VHDL-2008 all we need to know is that it is now included in VHDL! Standard packages are included in VHDL

A package in VHDL is a collection of functions, procedures, shared variables, constants, files, aliases, types, subtypes, attributes, and components. A package file is often (but not always) used in conjunction with a unique VHDL library.
