We've added -l
option to specify the lower-bound of unrolling depth. Sorry for breaking the backward compatibility..
Thanks Soonho. I was just thinking that you have already specified -u
to define an upper bound so you could probably leave -k
option without any changes. It causes some difficulties for me as I will have to identify dReach
version to choose appropriate command line arguments (which is not very easy as dReach
does not have a --version
option). However, if you need -k
to be the upper bound I will deal with this problem on my end.
Again, sorry for the confusion.
@scungao and I talked about the issue. Our conclusion is to respect the original meaning of -k
in BMC, which is an upper-bound of unrolling depth.
which is not very easy as dReach does not have a --version option
I understand. If you want, we can add --version
option to dReach of course. At the same time, however, I'm wondering why you keep multiple versions of dReach.
Hi Fedor, the change on the -k option is to follow the standard meaning of this parameter in model checkers. Do you need to use previous versions of dReach -- in other words, are there cases where some old version significant outperforms the new version?

I was just checking if ProbReach
works with all released versions of dReach
. It is not a big problem. I will handle it. Thank you.
I noticed that in the new version of
dReach
-k
and-u
are used to specify an upper bound of unrolling. Is it possible to change-k
option to define the exact number of unrolling steps (as it was used before)?
