Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Self-Aligned Double Patterning (SADP) is being considered for use at the 10$nm$ technology node and below for routing layers with pitches down to ~50nm because it has better LER and overlay control compared to other multiple patterning candidates. To date, most of the SADP-related literature has focused on enabling SADP-legal routing in physical design tools while few attempts have been made to address the impact SADP routing has on local, standard cell (SC) I/O pin access. ,  present the first study on SADP-aware pin access and layout optimization at the SC level. Accounting for SADP-specific design rules,  propose a coherent framework that uses Mixed Integer Linear Programming (MILP) and branch and bound method to simultaneously optimize SADP-based local pin access and within-cell connections. Our experimental results show that, compared with the conventional approach, our framework effectively improves pin access of the standard cells and maximizes the pin access flexibility for routing.
