I could describe how to do it, but it would be far better to point 
you in the direction of the help file first, which is found in ISIS's 
Help->Proteus VSM Help.  There is a whole section on working with 
microprocessors.  If you've used Proteus enough to simulate non-
programmable circuits, then the AVR simulation isn't a big step.
I would, however offer the following advice:
The more recent models (from the 'AVR2' library) simulate the reset 
pin as open=low, so for the Mega series, tie it high or your 
simulation won't run.
This is based on using AVR Studio and WinAVR - Save your Proteus work 
in the same directory as the .aps of you project and load the .elf 
file into the AVR.  That way you get source-level debugging.

If you have problems using it (and you have a legal copy of Proteus), 
I recommend going to Labcenter's user forums here:
