Cocoon: An Infrastructure for Integrated EDA

Cocoon is an open-source infrastructure for integrated EDA with interoperability and interactivity. It contains a set of cross-tool interfaces and plays the role of EDA agent that can help IC designers choose EDA point tools to assemble a legal design flow and to produce ICs with a higher quality of results (QoR). It can also help EDA researchers and tool developer research new design methodology and cross-stage optimization.
