Struct volute::sop::Sop

pub struct Sop { /* private fields */ }

Sum of Products representation (Or of And)

This is the usual representation for 2-level logic optimization. Any boolean function can be represented this way, and the optimization can be done quite efficiently (with Espresso, for example).
