PowerPC Simulation

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.

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.

Check out answer records 17088 and 17013. Unfortunately the example file in the answer record will not compile with ModelSim 6.2f. Got a webcase open for that.
