Abstract: Disclosed is a method wherein selective voltage binning and leakage power screening of integrated circuit (IC) chips are performed. Additionally, pre-test power-optimized bin reassignments are made on a chip-by-chip basis. Specifically, a leakage power measurement of an IC chip selected from a voltage bin can is compared to a bin-specific leakage power screen value of the next slower voltage bin. If the leakage power measurement is higher, the IC chip will be left in the voltage bin to which it is currently assigned. If the leakage power measurement is lower, the IC chip will be reassigned to that next slower voltage bin. These processes can be iteratively repeated until no slower voltage bins are available or the IC chip cannot be reassigned. IC chips can subsequently be tested according to testing parameters, including the minimum test voltages, associated with the voltage bins to which they are finally assigned.

Abstract: Various embodiments include approaches for analyzing a customer design for an application specific integrated circuit (ASIC). In some cases, an approach includes: determining performance requirements of the customer design; querying a test screen database for the performance requirements of the customer design, the test screen database having failure thresholds and associated test screens for detecting the failure thresholds for a set of ASIC devices; generating a filter database including select failure thresholds and associated test screens for the performance requirements of the customer design; and selecting a set of test screens from the filter database based upon a yield cost criteria in forming the ASIC.

Abstract: Words of data are maintained in content-addressable memory cells arranged in rows. Two of the rows are timing reference rows, and the remainder of the rows are data rows that maintain the words of data. The data rows form individual matchlines. A first of the reference rows forms a precharge reference matchline, and a second of the reference rows forms an evaluation reference matchline. The timing for the individual matchlines to precharge is based on the time to precharge the precharge reference matchline, and timing for the individual matchlines to evaluate a search word is based on the time for the evaluation reference matchline to evaluate the search word.
