I am interested in adding a "busy" signal to the Input/Ouptut port of
the Picoblaze. This will allow me to add a Wishbone wrapper to the
picoblaze and allow me to used some free wishbone cores from
Opencores.org.

Since the picoblaze is written using xilinx primatives the VHDL code
is a little hard to follow. On to my question:

Has anyone put together a block diagram of the internal signal
connections of the picoblaze?

The Xilinx documantation I've seen doesn't "pictorially" show the
internal signal connections.

I'm willing to look through the code and put together a diagram, but
if someone else has done it and could save me some time... great!

Thanks,
