Abstract
Some embodiments of the present invention overcome I/O bottlenecks of an EDA work flow by keeping layout data distributed during handoffs among different processing stages. Specifically, some embodiments leverage a concurrent computation paradigm where data is propagated incrementally between stages, and where data processing among consecutive stages and the I/O between stages are executed concurrently. Specifically, different data processing stages can partition the layout data differently, and portions of the layout data that are not required by a data processing stage can be either passed-through or passed-around the data processing stage.
