SMT Slides

We will upate the slides during the semester and they are not considered to be complete until the end of the semester.

Exercises

Exercises start two weeks later. Organization will be announced at the end of the lecture on October 8th and/or can be found here.

Times, rooms and group assignments may be found on the KUSSS page of this course (342.236).
Details on the organization of the exercises may be found below.

Predicate abstraction checks for simple example on the slides in SMT2 syntax: pred0.smt, pred1.smt, pred2.smt, pred3.smt, pred4.smt, pred5.smt. All should be 'sat', except for the last one pred5.smt, where we assume i != INT_MAX. The check pred2.smt actually shows, that we would need "b = *;" instead of "if (b) b = *;" if we consider bit-precise reasoning (so 32 bit 2-complement int and not integers).

C32SAT is a satisfiability checker for boolean C expressions. It can check whether they can be satisfied, are tautological, or can potentially be undefined according to the C99 standard.
