Abstract
We demonstrate how to use placement to ameliorate the predicted repeater explosion problem caused by poor interconnect scaling. We achieve repeater count reduction by dynamically modifying net weights in a context-sensitive manner during global placement and coarse legalization. Our scheme, which models layer assignment as well as valid inter-repeater distance ranges, can decrease the repeater counts significantly with minimal impact on wirelength.
