3.1i Foundation ISE: Using user defined packages in VHDL files

描述

Keywords: library, package, XST, Project Navigator

Urgency: Standard

General Description:
The VHDL language is compile order dependent, so users
who want to have packages utilized by entities must consider
the following.

解决方案

If the package is going to be referenced by one entity, the package
must be placed above the entity in the file.

If the package is going to be referenced by more than one entity, the
package must be placed in a separate file and compiled before any
of the entities utilizing the package.
