Abstract
A system and method of connecting a macro cell to a system power supply network is disclosed. In a particular embodiment, the method includes determining a distance of an edge of the macro cell from a power line or a ground line of the system power supply network. The method further includes selectively adding at least one line to the system power supply network.
Claims25
A method for automatically connecting a macro cell having an internal power supply network to a system power supply network, the method comprising:
- determining a distance of an edge of the macro cell from a power line or a ground line of the system power supply network;
- and
- selectively adding at least one line to the system power supply network.
A method comprising:
- detecting an edge of an internal power supply network of a first macro cell;
- examining a region proximate to a boundary of the first macro cell for a second macro cell;
- when a second macro cell is detected within the region, connecting an internal power supply network of the second macro cell to the internal power supply network of the first macro cell when the first and second macro cells are aligned with matching polarities;
- when the second macro cell is not detected within the region and when the edge of the internal power supply network of the first macro cell exceeds a threshold distance from a first line of the system power supply network, adding at least a second line coupled to the system power supply network.
A processor readable medium containing processor executable instructions that are operative to cause a processor to:
- receive data representing a circuit including a first macro cell and a system power supply network;
- in response to an edge of an internal power supply network of the first macro cell exceeding a threshold distance from a first line of the system power supply network, automatically add at least one line coupled to the system power supply network;
- and
- store data representing the circuit including the at least one line.
A processor readable medium containing circuit design data that is configured to be processed by a circuit fabrication system to fabricate a circuit, wherein the circuit design data includes an internal supply network of a first macro cell that exceeds a threshold distance from a system power supply network, and at least one additional line is coupled to the system power supply network proximate to the first macro cell wherein the at least one additional line is automatically generated by a physical design tool in response to detecting the threshold distance in exceeded, and the circuit design data further comprises a connection between an internal power supply network of a second macro cell to the internal power supply network of the first macro cell where the first macro cell and the second macro cell are aligned with matching polarities.
