    摘要: The present invention relates to a method and respective system for operating a DRAM main memory. One buffer line is provided for multiple pages. When writing data to the buffer it is decided which to which buffer-line the data is written to based on its destination main memory address. A tuple consisting of lower memory address and data is stored. Data entered into the buffer-line will be sorted by page in case the line is flushed to the main memory. Sorting the buffer entries results in less page openings and closings, since the data is re-arranged by memory address and therefore in logical order. By using one line for multiple pages only a fraction of memory of a common set-associative cache is needed, thus decreasing the amount of overhead significantly.

    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 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.
