@cindex Zilog Z8000 simulator
When configured for debugging Zilog Z8000 targets, _GDBN__ includes a Z8000
simulator.
@table @code
@item target z8ksim
@kindex z8ksim
This debugging target is a simulator for the Z8002, the unsegmented
variant of the Z8000 architecture.
@end table
@noindent
After this point, you can debug Z8000 programs in the same style as
programs for your host computer; use the @code{file} command to load a
new program image, the @code{run} command to run your program, and so
on.
As well as making available all the usual Z8000 registers (see
@code{info reg}), this debugging target provides three additional items
of information as specially named registers:
@table @code
@item cycles
Counts clock-ticks in the simulator.
@item insts
Counts instructions run in the simulator.
@item time
Execution time in 60ths of a second.
@end table
You can refer to these values in _GDBN__ expressions with the usual
conventions; for example, @w{@samp{b fputc if $cycles>5000}} sets a
conditional breakpoint that will suspend only after at least 5000
simulated clock ticks.
