simulated target

[msarasa@fh-konstanz.de]

I have to make Gdb work with a simulated target instead of with the real 
target that works now. What should I do, tell me please the steps I may follow 
in order to change the real target that we use now via serial link for a 
simulated target . I have the simulator , but i've no idea how to begin. Does 
anybody have done that yet? could i see some code? or , how to begin? It's 
very important, please, i need that for my Thesis. 
Vielen Dank, Thank you very much
