General Description:
When creating post-configuration BSDLs, there is a syntax error in the way BOUNDARY_REGISTERs are defined:
===============
attribute BOUNDARY_REGISTER of comp62_ise : entity is
" 0 (BC_1, *, internal, 0)" & <---------- There is no COMMA after the )
.....
.....
" 299 (BC_1, IO_0, INPUT, X),"; <---------- This COMMA after the ) is NOT necessary
================
Because of the above two syntax errors, JTAG Instruction might fail.
To work around this problem, modify the BSDL file manually.
This problem has been fixed in the latest 6.3i Service Pack available at:

The first service pack containing the fix is 6.3i Service Pack 1.
