Abstract
Route segments of a set of nets may be grouped into route groups. Terminals of the set of nets may be grouped into terminal groups. For each net in the set of nets, a net signature may be determined based on route groups associated with the net and terminal groups associated with the net. The set of nets may be grouped into net groups based on the net signatures.
Claims20
A method, comprising:
- grouping, by a processor, route segments of a set of nets into route groups;
- grouping terminals of the set of nets into terminal groups;
- for each net in the set of nets, determining a net signature for the net based on route groups associated with the net and terminal groups associated with the net;
- and
- grouping the set of nets into net groups based on the net signatures.

A system, comprising:
- a memory storing instructions;
- and
- a processor, coupled with the memory and to execute the instructions, the instructions when executed cause the processor to:
- group route segments of a set of nets into route groups;
- group terminals of the set of nets into terminal groups;
- for each net in the set of nets, determine a net signature for the net based on route groups associated with the net and terminal groups associated with the net;
- and
- group the set of nets into net groups based on the net signatures.
5 more elements
A non-transitory computer-readable medium comprising stored instructions, which when executed by a processor, cause the processor to:
- group route segments of a set of nets into route groups;
- group terminals of the set of nets into terminal groups;
- for each net in the set of nets, determine a net signature for the net based on route groups associated with the net and terminal groups associated with the net;
- group the set of nets into net groups based on the net signatures;
- assign priorities to the net groups;
- and
- perform repeater insertion on the net groups in accordance with the assigned priorities.
