Abstract
An alternative wiring scheme uses information about pre-analyzed logic patterns to determine alternative wires for new logic networks. Preferably, no Boolean implication is used.
Claims13
In an information processing system, a method for alternative wiring for logic design, the method comprising:
- maintaining information descriptive of alternative wiring for each of multiple predetermined logic patterns;
- for a logic network, determining a portion of the logic network as corresponding to one of the multiple predetermined logic patterns;
- and
- determining an alternative wire for the logic network based on information maintained in the maintaining step that is descriptive of alternative wiring for the one of the multiple predetermined logic patterns.

A system for alternative wiring for logic design, the system comprising:
- means for maintaining information descriptive of alternative wiring for each of multiple predetermined logic patterns;
- means for determining, for a logic network, a portion of the logic network as corresponding to one of the multiple predetermined logic patterns;
- and
- means for determining an alternative wire for the logic network based on information maintained by the means for maintaining that is descriptive of alternative wiring for the one of the multiple predetermined logic patterns.
1 more element
A method for computer-aided design, comprising:
- determining a logic design including selecting predetermined logic building blocks for inclusion into the logic design, wherein the predetermined logic building blocks have been pre-analyzed for alternative wiring, and alternative wiring information is available for the predetermined logic building blocks;
- recording retrieval information for a portion of the logic design that is from one of the predetermined logic building blocks, wherein the retrieval information enables later look-up of alternative wiring information for the portion of the logic design, wherein the alternative wiring information for the portion of the logic design is from the alternative wiring information that is available for the predetermined logic building blocks.
