Scott,
Thanks for your answer...

Well, thats a good point but didn't come into my mind. What I had in my
mind was simulating the target interface. The user, who is some day
developing software for the PIC target, expects to be able to see in the
klogic work sheet what happens in the real target: When a signal goes
high the corresponding wire in the schematic should go red. I intend to
put klogic and the target to communicate with each other so that this
kind of live debugging is possible. However, as I have no real hardware
PIC target, I'm looking forward to be able to simulate this behaviour
with gpsim.
I think I should be able to get the idea how to do the above from the
gpsim sources and examples. But this next one may be trickier: I'd like
to download the generated code into the target directly from the klogic.
To simulate the target in this regard may be more challenging, at least
for me.
Timo
