If an ABEL file that includes Test Vectors is added to an ISE Project, the Test Vectors should appear in the Sources in Project window beneath the ABEL source file. However, if the DEVICE keyword is used in the ABEL file, test vectors do not appear.
The DEVICE keyword prevents the test vectors from being displayed in Project Navigator. You can remove or comment out the DEVICE line to view and run simulation processes on the test vectors.
In ISE 6.1i and later software, the DEVICE keyword is not used.
