Hi all
I found nandsim has delay options like access_delay ( read delay ),
program_delay( write delay ) and erase_delay.
Does it guarantee delay time strictly?
It seems that nandsim would allocate memory using vmalloc function.
those memory spaces could be swapped out.
When I set access_delay to 20us,
If required data was in hard disk, nandsim could not finish required
operation in given delay time because read data from hard disk takes
longer time than 20us.
How resolve this problem in nandsim?

No, this option is not working and should be fixed or kicked out.
