Have you looked at xapp717? They connect a few registers to the ppc
using a "subset" of the apu interface, and it only takes a page or so
of code.

I thought about APU but its kind a hard because all i want to do is to
hook my SYSGEN based model to PLB. I am sure there must be a easier way
its just i ma not aware

The APU might work well for that. It's closer to the FSL than the PLB
and OPB are, and it's faster. But I'm assuming your PPC405 is in a V4
...

Any buddy know how the following can be done.

I need to connect the model developed in sysgen to EDK desgin. The EDK
design has PowerPC405 so EDK Pcore block in Sysgen is useless as it
only supports FSL for microblaze...

Any suggestion how it can be done... Only objective is to integrate
some model developed to PLB bus in EDK as user core
