Description Marius Mikučionis 2018-05-09 10:50:33 CEST
Suppose a trivial model with one declaration:

clock tg;

The following properties are satisfied:

E<> tg>=0
Pr[<=2] (<> tg>=0)

But the following fail:

simulate 1000 [<=2] { tg } : 1 : tg>=0
simulate 1000 [<=2] { tg } : 1 : 0<=tg

this one succeeds 100%:

simulate 1000 [<=2] { tg } : 1000 : 0<tg

so it seems that the issue is somehow connected with strictness of the constraint.
