Instantiation and picoblaze

Hello,

I probably do it without realising in my other VHDL, but im confused
now.

Basically I have picoblaze on a board and I would like to write some
elements in VHDL to interact with picoblaze, I have heard that I need
to Instantiate picoblaze to be able to do this?

Can anybody show me the correct way to do this, as in, a simple couple
of lines of VHDL to write something to the in_port of picoblaze?

Thanks

David
