Circuit design routing using multi-panel track assignment

A device comprising:

• a memory storing instructions;
• and
• a hardware processor communicatively coupled to the memory and configured by the instructions to perform operations comprising:
• routing a network of a circuit design based on a grid of cells that divides the circuit design and forms a plurality of consecutive panels, each panel in the plurality of consecutive panels comprising a defined row of cells of the grid of cells;
• and
• performing a track assignment for a set of wires of the network based on the plurality of consecutive panels, a first panel bound, and a second panel bound, the first panel bound defining a first set of consecutive panels relative to a particular panel of the plurality of consecutive panels, the second panel bound defining a second set of consecutive panels relative to the particular panel, and the second set of consecutive panels being larger than the first set of consecutive panels.

A non-transitory computer-readable medium comprising instructions that, when executed by a hardware processor of a device, cause the device to perform operations comprising:

• routing a network of a circuit design based on a grid of cells that divides the circuit design and forms a plurality of consecutive panels, each panel in the plurality of consecutive panels comprising a defined row of cells of the grid of cells;
• and
• performing a track assignment for a set of wires of the network by:
• grouping the set of wires according to the plurality of consecutive panels to produce a plurality of wire panel groups;
• determining a number of assignment rounds based on a number of panels falling within a second panel bound;
• and
• scheduling, based on a plurality of assignment rounds, a plurality of threads to perform track assignment on the plurality of wire panel groups based on a first panel bound, and the second panel bound, the first panel bound being smaller than the second panel bound, and the plurality of assignment rounds comprising the determined number of assignment rounds.
