We present a method for model-checking of safety and liveness properties over procedural programs, by combining state and ranking abstractions with procedure summarization. Our abstraction is an augmented finitary abstraction [KP00,BPZ05], meaning that a concrete procedural program is first augmented with a well founded ranking function, and then abstracted by a finitary state abstraction. This results in a procedural abstract program with strong fairness requirements which is then reduced to a finite-state
fair discrete system
(
fds
) using procedure summarization. This
fds
is then model checked for the property.
