Implementing Z directional macro port assignment |
摘要 |
A method, system and computer program product are provided for implementing an enhanced Z-directional macro port assignment or three-dimensional port creation for random logic macros of heterogeneous hierarchical integrated circuit chips. An initial port placement is provided on a layer for a macro. The initial port placement is expanded to provide a three-dimensional port shape including a plurality of metal layers along a z-axis. Wire routing of each of the macro level and a chip top level is defined within the expanded three-dimensional port shape. Each unnecessary metal layer of the expanded three-dimensional port shape is removed, providing a final three-dimensional port shape.
