WebMay 21, 2015 · We present the synthesis through unification (STUN) approach, which is an extension of the counter-example guided inductive synthesis (CEGIS) approach. In CEGIS, the synthesizer maintains a subset S of inputs and a candidate program Prog that is correct for S. The synthesizer repeatedly checks if there exists a counter-example input c such … WebInductive Synthesis (CEGIS), that has been widely used in the emerging area of automatic program synthesis. We show how a LMI-based relaxation can be formulated within the CEGIS framework for synthesizing CLFs.

Counterexample-guided inductive synthesis (CEGIS) In enumerative CEGIS [33], counterexamples from failed candidates are used to generate reﬁnement lemmas: concrete instantiations of the speciﬁcation that the next candidate solu-tions must satisfy before being veriﬁed. Example 2: To synthesize the function f from Example 1,

Webtiality, and it extends counterexample-guided synthesis methods (CEGIS) [42] to hardware design. VeriSketch uses CEGIS to complete the sketch by breaking the synthesis problem into separate verication and synthesis sub-problems which can be solved by a SAT/SMT solver. In each ver-ication round, the solver searches for a counterexample which CEGIS is a form of generate and check, where a synthesizer generates candidate programs that are checked by an off-the-shelf checking procedure. The key idea in CEGIS, however, is to use a checkercapable of producing counterexample inputs. This allows us touse an inductive synthesis procedure instead of … See more One of the challenges in attempting full functionalspecification of behavior is that it can sometimesbe difficult to pin down what the expected … See more In contrast, a number of other synthesis approaches have been proposed that rely on the otherkinds of verification mentioned in the beginning: abstract interpretation, type-based analysis and deductiveverification. … See more The constraint-based techniques actually constitute a broad category of verification techniques, but the general setup is illustrated in the figure.
