“…VLSI layout patterns are significant resources for flows of various design for manufacturability (DFM) research, such as optical proximity correction (OPC) [7,10,13,15,26], layout hotspot detection [5,27,30,33,34], pattern matching [4], lithography simulation [16,17,31] and so on. However, VLSI layout pattern libraries are very often not available for research or testing due to the long and iterative technology life cycle, especially in the initial stage, which may slow down the technology node development [10].…”
