Abstract :
A practical online design rule checking system is proposed. which can provide the following features: an ability to cope with a complicated and wide variety of design rules with high accuracy, easy use, high-speed incremental DRC (simultaneous checking with pattern editing) and total DRC (nonsimultaneous checking), high-speed pattern editing, and a small memory space. For the last three items, a field block data structure is developed. Experimental results show that this system is effective for VLSI cell layout design
