in the sources and in the "manual".

Note that in order to be both attractive and efficiently coded,
one has to take ultra-wide register sizes from the start.
If you don't code with more than 64-bit sizes in mind,
then your simulator will have to be recoded (and maybe
rearchitectured) later. You can also probably look at
other's implementations.


have fun !
