Hi all,

Has someone tried to attach an user logic core to the OPB bus of
MicroBlaze
using EDK 6.1?

In this new version of EDK there is a new constant called PIPELINE
MODEL that you can find in the user core reference design.

Here you are the options that it gives you:

--USER-- change PIPELINE_MODEL constant below to desired pipeline
model for
--       user logic:
--          1 = include OPB-In pipeline registers
--          2 = include IP pipeline registers
--          3 = include OPB-In and IP pipeline registers
--          4 = include OPB-Out pipeline registers
--          5 = include OPB-In and OPB-Out pipeline registers
--          6 = include IP and OPB-Out pipeline registers
--          7 = include OPB-In, IP, and OPB-Out pipeline registers


Does anybody know where can I find some information related to this?

Thanks in advance, 

Arkaitz.
