    摘要: Disclosed is a method that predicts test yield for a semiconductor product, prior to design layout. This is accomplished by applying a critical area analysis to individual library elements that are used to form a specific product and by estimating the test yield impact of combining these library elements. For example, the method considers the test yield impact of sensitivity to library element to library element shorts and the test yield impact of sensitivity to wiring faults. The disclosed method further allows die size growth to be traded off against the use of library elements with higher test yield in order to provide an optimal design solution. Thus, the method may be used to modify library element selection so as to optimize test yield. Lastly, the method further repeats itself at key design checkpoints to revalidate initial test yield (and cost) assumptions made when the product was quoted to a customer. Thus, the method provides increased accuracy of test yield estimate from initial sizing through design and further allows designs to be modified to improve test yield.

    摘要: Disclosed are embodiments of a method, service, and computer program product for performing yield-aware IC routing for a design. The method performs an initial global routing which satisfies wiring congestion constraints. Next, the method performs wire spreading and wire widening on the global route, layer by layer, based on, for example, a quadratic congestion optimization. Following this, timing closure is performed on the global route using results of the wire spreading and wire widening. Post-routing wiring width and wire spreading adjustments are made using the critical area yield model. In addition, the method allows for the optimization of already-routed data.

    摘要: Disclosed is a method and system for inserting redundant paths into an integrated circuit. Particularly, the invention provides a method for identifying a single via in a first path connecting two elements, determining if an alternate route is available for connecting the two elements (other than a redundant via), and for inserting a second path into the available alternate route. The combination of the first and second paths provides greater redundancy than inserting a redundant via alone. More importantly, such redundant paths provide for redundancy when congestion prevents a redundant via from being inserted adjacent to the single via. An embodiment of the method further comprises removing the single via and any redundant wire segments, if all of the additional vias used to form the second path can be made redundant.

    摘要: The invention provides a method and structure for optimizing placement of redundant vias within an integrated circuit design. The invention first locates target vias by determining which vias do not have a redundant via. Then, the invention draws marker shapes on or adjacent to the target vias. The marker shapes are only drawn in a horizontal or vertical direction from each of the target vias. The invention simultaneously expands all of the marker shapes in the first direction to a predetermined length or until the marker shapes reach the limits of a ground rule. During the expanding, different marker shapes will be expanded to different lengths. The invention determines which of the marker shapes were expanded sufficiently to form a valid redundant via to produce a first set of potential redundant vias and the invention eliminates marker shapes that could not be expanded sufficiently to form a valid redundant via.

Each of the four channel regions is directly adjoined to one of the four photodiodes and the common floating diffusion region. The four photodiodes are located within four different quadrants as defined employing a vertical line passing through a point within the common floating diffusion region as a center axis. The common floating diffusion region, a reset gate transistor, a source follower transistor, and a row select transistor are located within four different quadrants as defined employing a vertical line passing through a point within one of the photodiodes as an axis.
