Hi, everybody

I was reading the guide to integrate eclips+gnuarm+gdb and it is really 
very good. Very simple to understand and yet very complete.
But I have a question. Is it possible with the tools shown in that 
tutorial or maybe with some other not mentioned to do a simulated 
debugger ? I want to test my routines but i don't have the hardware. so 
i want a simulator. Well I have the hardware, but it don't have the jtag 
pins available and the routines that I want to verify can be tested just 
in a input/output check.
I want something like the MPLAB IDE can do for PICs.

Thanks, Mauricio
