---|
9 | Description [This file contains the functions to check invariant properties |
---|
10 | by the PureSAT abstraction refinement algorithm, which is entirely based on |
---|
11 | SAT solver, the input of which could be either CNF or AIG. It has several |
---|
12 | parts: |
---|
13 | |
---|
14 | * Localization-reduction base Abstraction |
---|
15 | * K-induction or interpolation to prove the truth of a property |
---|
16 | * Bounded Model Checking to find bugs |
---|
17 | * Incremental concretization based methods to verify abstract bugs |
---|
18 | * Incremental SAT solver to improve efficiency |
---|
19 | * UNSAT proof based method to obtain refinement |
---|
20 | * AROSAT to bring in only necessary latches into unsat proofs |
---|
21 | * Bridge abstraction to get compact coarse refinement |
---|
22 | * Refinement minization to guarrantee minimal refinements |
---|
23 | * Unsat proof-based refinement minimization to eliminate multiple candidate |
---|
24 | by on SAT test |
---|
25 | * Refinement prediction to decrease the number of refinement iterations |
---|
26 | * Dynamic switching to redistribute computional resources to improve |
---|
27 | efficiency |
---|
