Implementation set-based guide engine and method of implementing a circuit design

A method of implementing an integrated circuit design can include the steps of forming a base implementation set and forming a guide implementation set having a plurality of guide implementation set nodes. The method can further include the steps of depositing directives on at least one guide implementation set node (or each node) among the plurality of guide implementation set nodes. The method can further include the steps of creating and depositing tasks on at least one guide implementation set node (or each node) among the plurality of guide implementation set nodes. The method can further include the steps of invoking each task deposited on guide implementation set nodes as each node in the guide implementation set tree is visited.
