That's actually quite a difficult approach to take as you aren't able to
fully simulate how the hardware interacts with the system, making concerns
like timing very difficult to accurately model. A better approach is to
tie into a full system simulator -- qemu makes it very easy to add a new
pci device into the system. This way your hardware simulator doesn't have
to worry about the complexities of kernel programming, and the resulting
device drivers doesn't need hooks for the simulator as it would see the
pci device as if it were installed in a system.
Btw, do you know of any inexpensive ways to be introduced SystemC
development on FPGAs? Cheers,
