A unified logic optimization method efficient at handling both AND/OR-intensive and XOR-intensive functions is proposed. The method is based on iterative BDD decomposition using various dominators. Detail analysis of decomposable BDD structures leading to AND/OR, XOR and MUX decompositions are presented. Experiment shows that our synthesis results for AND/OR-intensive functions are comparable to those of SIS, and results for XOR-intensive functions are comparable to those of techniques targetting specifically XOR decomposition
