Hi,
Chun Lin,
RAMB4_S16_S16.v is part of the xilinx library so if you have Xilinx
Foundation installed, it is part of it. You'll need this tool anyway if you want
to implement MAC in Xilinx chips. Similar goes for glbl.v
art_hsdp_256x40.v is part of the Artisan library and is usefull if you
intend to use MAC in ASIC.
For
simulation purposes generic_tpram.v is enough. It is just a simulation model and
is attached to this model. You can also find it on cvs. Look here: http://www.opencores.org/cvsweb.shtml/common/generic_memories/rtl/verilog/
Regards,
Igor
