I actually implemented a PPC440 inside my existing ISE(11.4) project and i would like to share some signals between my entire code in ISE and some code inside the PPC.
What i see in XPS is that i can input or output some signals from or to ISE if i map them with an address in the UCF.
But i don't want to output or input them, i just want a bus (not in the ucf) that can be share between my code in ISE(vhdl) and my code in the PPC(c).
I though it should be really simple, but i was not able to find anything on the net.
Thanks for your help.
