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
