BSDL Files - Where do I find IEEE 1532 BSDL files?

Description

Where do I find IEEE 1532 BSDL files?

How do I distinguish between an IEEE 1532 BSDL file and an IEEE 1149.1 BSDL file?

Solution

IEEE 1149.1 BSDL File Notation

The IEEE 1149.1 BSDL files appear as: <device_name>.bsd

For example: xc2s200e.bsd

IEEE 1532 BSDL File Notation

The IEEE 1532 BSDL files appear as: <device_name>_1532.bsd

For example: xc2s200e_1532.bsd

NOTE: Do not use Prototype IEEE Std 1532 BSDL files in place of or alongside 1149.1 BSDL files.

Prototype IEEE Std 1532 BSDL files also contain the following comments in the header section of the file:

This file conforms to the unapproved IEEE Standard 1532 BSDL draft
Standard. It may not function as expected with IEEE 1149.1 BSDL
and is subject to change pending the ratification of the 1532 Standard
by the IEEE. When denoted as FINAL, it has been verified
syntactically, and against hardware.
