Accelerating Computational Lithography With GPU Rasterization

By Loay Hegazy, Mohamed Taher, and Sherif Hammouda Semiconductor manufacturing at advanced nodes has become a race against physics. Even as feature sizes shrink, the tools that design and validate these circuits must operate with precision and speed. We show in a recent research paper that one part of the post-tapeout flow, rasterization, can be significantly sped up by deploying GPUs for massively parallel processing. The challenge: Rasterization at the nanometer scale Rasterization is the proc
