I think you are referring to hardware model debugging and logging.
The QEMU "tracing" mechanism that Blue Swirl mentioned is a
DTrace/SystemTap style tool for observing QEMU internals and not what
you are looking for.

QEMU is not cycle-accurate and typically only presents the
register-level hardware interfaces to the VM.  We don't necessarily
model hardware state and connections.  However, the QEMU User Forum
link that Blue Swirl posted includes information from people who are
using QEMU for similar purposes as you.
