Hi,

First I want to thank all of those who have contributed to make this
simulator.  It is a great tool!

I am not sure if this makes sense to you or not, but I have tinkered with
Simulavr 1.1dev and added files to support the ATTINY4313.  I believe it is
functioning OK as I basically took the ATTINY2313 files and augmented them for
the increased memory.  I know there are some other slight differences in terms
of the registers (for example PCINT now has PCINT0, PCINT1 and PCINT2 on
ATTINY2313a and ATTINY4313) but I am not sure how to augment them.  Also for
the stack I increased the 8 to 16 as I was not able to flash my program
properly.  I am not sure if 16 is the right value but 8 was too small :-)
(stack = new HWStackSram(this, 16);).

As you can tell by this point, I am a novice and probably know just enough to
get myself into trouble. 

My variant of attiny4313 seems to simulate my program well enough, but I
certainly know that it would be great to have someone knowledgeable look at my
attempt and correct it for the register changes, etc.

Thanks,
James
