First, a SAT solver is used to determine whether the preimage solution has been exhausted. When a preimage solution is generated by the SAT solver, a specific ATPG process is adopted to minimize the sets of assignments to state variables. This in turn reduces the number of all the preimage solutions and accelerates the fixed point iteration process.

SAT用来判断是否已经穷尽所有解；每次SAT枚举出一个前像解后，采用一个专门的ATPG过程减少状态变量上的赋值，从而减少前像解的总个数，加快后面的不动点迭代处理。
