While Model Checking, to obtain a specific (symbolic) state s in a set S, one would want to use the PickOneCube(S) function. Yet to only obtain a single state, the resulting cube needs to fix a value for each variable. Hence, I would then want to provide some cube c of all states (similar to the Exists function).
Yet, doing so returns a non-symbolic vector of assignments which I have to convert back into a BDD.
inline sylvan::Bdd
satone(const sylvan::Bdd& f, const sylvan::Bdd& c)
{
const auto f_vals = f.PickOneCube(c);
const auto c_vars = sylvan::BddSet(c).toVector();
sylvan::Bdd res = top();
for (int i = c_vars.size() - 1; 0 <= i; --i) {
const int var = c_vars[i];
const bool val = f_vals[i];
res &= val ? ithvar(var) : nithvar(var);
}
return res;
}As you are working towards v2.0, I would propose this is changed to return a sylvan::Bdd instead. If the user wants to have these values output instead then they can provide a begin iterator to some data structure they would like to feed the result into.
