There's a note about this hidden at the bottom here:

  http://savannah.nongnu.org/download/simulavr/doc/html/simulavr_5.html#SEC5

Basically, just give gdb this command:

  (gdb) signal SIGHUP

Note that this is unique to simulavr for now.

:) If I only issue the "load" command it doesn't seem that the device is being
:) reset, because the BSS section is clobbered from previous accesses, but the
:) start-up code should clear the BSS section.

The load command only uploads the program into the simulator's flash
space. It doesn't change any registers (including the PC).

There's a few other ways to reset:

  (gdb) set var $pc = 0x0

or

  (gdb) jump *0x0

Here's the reference:
