20080307374 | METHOD, SYSTEM, AND COMPUTER PROGRAM PRODUCT FOR MAPPING A LOGICAL DESIGN ONTO AN INTEGRATED CIRCUIT WITH SLACK APPORTIONMENT - A logical design including multiple logical blocks is mapped onto an integrated circuit chip. A chip level floor plan is created on the chip, including temporary areas on the chip set aside for accommodating logical blocks having logical content including timing requirements based on the logical design. The temporary areas are translated into physical cells on the chip with pins assigned for inputs and outputs for the logical blocks. The logical blocks are mapped to the physical cells on the chip in a time sensitive manner using timing assertions to form temporary logical partitions. Blocks on the chip, including the temporary logical partitions, are connected based on the timing assertions. A timing analysis is performed on the chip to determine timing slack associated with each temporary logical partition. A determination is made whether the timing slack is acceptable. If the timing slack is not acceptable, the slack is apportioned for, and apportioned slack information is fed back in the form of timing assertions. Mapping, connecting, performing a timing analysis, and apportioning for slack are repeated until the timing slack associated with each temporary logical partition is determined to be acceptable. | 12-11-2008 |

20100293512 | CHIP DESIGN AND FABRICATION METHOD OPTIMIZED FOR PROFIT - Disclosed is a computer-implemented method for designing a chip to optimize yielding parts in different bins as a function of multiple diverse metrics and further to maximize the profit potential of the resulting chip bins. The method separately calculates joint probability distributions (JPD), each JPD being a function of a different metric (e.g., performance, power consumption, etc.). Based on the JPDs, corresponding yield curves are generated. A profit function then reduces the values of all of these metrics (e.g., performance values, power consumption values, etc.) to a common profit denominator (e.g., to monetary values indicating profit that may be associated with a given metric value). The profit function and, more particularly, the monetary values can be used to combine the various yield curves into a combined profit-based yield curve from which a profit model can be generated. Based on this profit model, changes to the chip design can be made in order to optimize yield as a function of all of the diverse metrics (e.g., performance, power consumption, etc.) and further to maximize the profit potential of the resulting chips. | 11-18-2010 |
