ABSTRACT
In this paper, we present a mixed-height standard cell placement flow for digital circuit blocks. To our best knowledge, commercial tools currently do not support this type of flow in a fully automated manner. In our placement flow, we leverage a commercial placement tool and integrate it with several new point tools. Promising experimental results are reported to demonstrate the efficacy of our placement flow.
