Sun did not release BSDL for the OpenSPARC T1. The
OpenSPARC T1 release is for functional design, synthesis and Verification.
BSDL and other DFT information is very much
physical design dependent (e.g. BSDL order and Scan chains
are stitched based on placement of the cells)
and hence there is no plan to release BSDL and other DFT
related information.
