8.1i XST - Is the package NUMERIC_SIGNED supported?

説明

Keywords: XST, NUMERIC_SIGNED, NUMERIC_SIGNED, IEEE Library, packages

If you use packages such as NUMERIC_SIGNED and NUMERIC_EXTRA in the code:

USE ieee.NUMERIC_EXTRA.all;
USE ieee.NUMERIC_SIGNED.all;

you will receive the following error:

"ERROR:HDLParsers:oooo - "aaaa" Line xx. Library unit NUMERIC_EXTRA is not available in library ieee."

The XST User Guide specifies that these packages are supported.

ソリューション

This is a problem with the XST User Guide. These packages are part of the new VHDL-200X standards, and XST began support for these with ISE 8.2i.
