OPC on a single desktop: a GPU-based OPC and verification tool for fabs and designers

A computational lithography solution addressing accuracy, speed and affordability requirements is presented. In particular, the cost of computational hardware should be affordable and that the speed and accuracy of the algorithm should be sufficient to complete a full-chip computation overnight. Given the issues associated with present tools, the presented solution uses graphic processors (GPUs) as well as CPUs as computation hardware to achieve a breakthrough improvement in speed and affordability. Scalability to large scale clusters has been addressed so that the solution can be simultaneously used by chip designers as well as manufacturers to provide consistency.
