20110191731 | ZONE-BASED AREA RECOVERY IN ELECTRONIC DESIGN AUTOMATION - Some embodiments provide a system that facilitates the creation of a design in an electronic design automation (EDA) application. During operation, the system determines a processing order for processing a set of cells in the design. In some embodiments, the processing order can be a reverse-levelized processing order. Next, the system may select a cell for performing area recovery according to the processing order. The system may then tentatively perform an area-recovery operation on the selected cell. Next, the system may determine a zone around the selected cell. Next, the system may propagate arrival times within the zone to obtain updated slack values at endpoints of the zone. The system may compute one or more timing metrics at the endpoints. If the updated slack values do not degrade the timing metric(s) at the endpoints, the system may accept the area-recovery operation of the selected cell. | 08-04-2011 |

Specifically, the system can overlay the design floorplan with a grid, wherein the grid comprises a set of grid cells and uses the grid cells as the set of regions. The grid can be associated with a predetermined number of rows and a predetermined number of columns. The system can determine the utilization of the region by calculating the utilization as a cell area of the region divided by a placement area of the region. The utilization can be incrementally calculated during the creation and optimization of the design. | 08-04-2011 |

If so, the system can reject the optimizing transformation. Otherwise, the system can determine whether applying the optimizing transformation to the logic gate degrades the timing metric in the circuit design. If so, the system can reject the optimizing transformation. Otherwise, the system can accept the optimizing transformation. | 08-04-2011 |

Some embodiments determine an order for processing the gates in the library or for processing input pins of a gate to facilitate early rejection of a candidate gate in the library of gates. In some embodiments, the evaluation of the impact of a candidate gate transformation is done progressively and level-by-level only up to the point where the gate transformation degrades one or more metrics. | 06-06-2013 |

20130145337 | DELTA-SLACK PROPAGATION FOR CIRCUIT OPTIMIZATION - Systems and techniques for optimizing a circuit design are described. When a selected gate is transformed during optimization, it causes a slack value at a pin of the transformed gate to change. The change in the slack value, called the delta-slack, is then propagated through a transitive fanin cone and a transitive fanout cone of the transformed gate to compute the new slack values at all the affected pins of the design. Some embodiments update slack values without propagating arrival and required times, and also without repeatedly evaluating timing arcs to compute gate delays. The updated slack values can be used to compute timing metrics. The timing metrics can be used to decide whether or not to commit the gate transformation to the circuit design. | 06-06-2013 |
