Abstract
A method of producing a flexible timing-driven routing tree is provided. Two or more target nodes are sorted in accordance with data criticality. A source-sink grid is built from one or more source nodes and the two or more target nodes. An initial routing tree is built comprising the one or more source nodes. A routing tree generation algorithm is executed on the initial routing tree, utilizing the sorted two or more target nodes and the source-sink grid in accordance with a user-defined timing factor to construct a flexible timing-driven routing tree. The user-defined timing factor specifies an extent of isolation for a routing path from a given one of the one or more source nodes to a given one of the two or more target nodes.
