This all depends on the level of hardware emulation that the simulator
supports. Does the simulator have full emulation of things like the
interrupt controller, UARTs, etc?

One approach we used in the past was for the simulator to connect its
UART device emulation to a TCP socket. We could then connect GDB to
that socket and treat it like a serial line. However, it was all very
slow because all debug interations were handled by simuated target
code.
