摘要： Techniques for storing and using compressed restrict values for selected scan chains and flip-flops, such that the states that need to be applied to those flip flops need not be solved by a linear equation system solver, such as a linear equation system solver provided by an automatic test pattern generation (ATPG) tool. Selected restrict values can then be injected into test patterns for those flip-flop combinations that need to be set in a certain shift cycle or those flip-flops that need to be initialized one after another (e.g., for serial settings in one scan chain).

摘要： In a method of encoding lines in a print from the skin and particularly a fingerprint, one line at a time is encoded by means of vertices, which include the starting point and the end point, that are situated on the line, in which case segments of connecting line between adjacent vertices are no more than a preset distance away from the line.

摘要： In a method and an arrangement for assessing the quality of skin print images, and particularly fingerprint images, provision is made for gradients to be formed for the individual picture elements (pixels) of the skin print image, for a mean value to be formed from the gradients of the pixels in one region of the image (tile) at a time, and for similarities in the mean values from tile to tile to form a measure of quality.

摘要： In a method for determining the bearing surface in images of skin prints, the skin having ridges and furrows and the images existing in the form of image data, the image is filtered with a plurality of Gabor filters whose cosine functions are oriented in different directions in the spatial domain. From the filter responses, surfaces are determined that are each distinguished by an approximate direction of the ridges/furrows, which direction is preset by the respective Gabor filter. The surfaces are combined to an overall surface that represents the bearing surface.

摘要： In a method of determining the region of interest in images of skin impressions, the skin having ridges and valleys and the images taking the form of image data, values within a first value range being assigned to the ridges and values within a second value range of the image data being assigned to the valleys, the values of the overall image are shifted in the direction of the first value range. The overall image is split into tiles. Mean values of the shifted values for the individual tiles are compared with a reference value. Those tiles whose mean value deviates relative to the reference value in the direction of the first value range are considered at least on a preliminary basis as belonging to the region of interest.

摘要： Techniques are provided for X-masking using at least some masking information provided by on-chip logic, in lieu of masking information provided from off of the integrated circuit being tested. The masking information is provided by a masking information source on the integrated circuit being tested, such as, for example, a read-only memory (ROM) circuit, that feeds the masking information to the X-masking logic. With these implementations of the invention, it is possible to perform X-masking independent from any external data, thus enabling X-masking for a logic built-in self-test without requiring an external testing device.
摘要翻译：使用由片上逻辑提供的至少一些掩蔽信息来提供用于X掩蔽的技术，以代替从正被测试的集成电路提供的屏蔽信息。屏蔽信息由正在测试的集成电路上的掩蔽信息源（例如，将只有读取存储器（ROM）电路）提供给X掩蔽逻辑的掩蔽信息提供。利用本发明的这些实施方式，可以独立于任何外部数据进行X-掩蔽，从而可以在不需要外部测试装置的情况下实现逻辑内置自检的X掩蔽。
