I am simulating the PowerPC and can't find the damn program counter. I have looked in the reference manuals that come with the EDK but can't find any helpful info!!
Anyone know where to point me? I am using ModelSim by the way.
Thanks!

You can't see it directly.
For early phases of design I make sure caches stay turned off and just follow memory fetches. It will be a mix of instructions and data of course, but it's better than nothing.
Note 99% of my PPC simulation experience has been with Freescale's MPC8245 full-functional model. That chip does have a neat feature where some additional debugging status pins help you trace the execution.
