    摘要: Circuit responses to a stimulus may be compacted, decreasing the number of pin outs, without increasing the circuit element length, using a compactor. In accordance with one embodiment of the present invention, errors may be detected in scan chains used for integrated circuit testing. The number of outputs applied to output pins or other connectors may be substantially decreased, resulting in cost savings.

    摘要: A method of constructing a standard cell library for double patterning lithography (DPL) includes dividing a standard cell into a first region determined not to have an interaction with an adjacent outer cell and a second region that is likely to have such an interaction, generating data representative of DPL patterns corresponding to the first and second regions, and generating a standard cell library made up of the data. The library is then accessed and used to form a DPL mask. The DPL mask can be used to form a pattern on a substrate made up of a layout of cells in which the pattern of the standard cell is duplicated at several locations in the layout.

    摘要: A compactor has a reduced number of outputs and the ability to handle a higher number of errors and unknown logic values. The procedure for designing the matrix and the resulting compactor involves determining the number of unknown logic values that may be encountered and adding columns to the compactor matrix based on the number of errors. Basically, the number of possible combinations of scan in lines is determined. Then, additional columns are added for each possible combination of scan in lines. The number of columns that are added for each combination of scan in lines is equal to the number of errors plus one in one embodiment.

    摘要: In a method of designing a system-on-chip including a tapless standard cell to which body biasing is applied, a slow corner timing parameter is adjusted to increase a slow corner of an operating speed distribution for the system-on-chip by reflecting forward body biasing, and a fast corner timing parameter is adjusted to decrease a fast corner of the operating speed distribution for the system-on-chip by reflecting reverse body biasing. The system-on-chip including the tapless standard cell is implemented based on the adjusted slow corner timing parameter corresponding to the increased slow corner and the adjusted fast corner timing parameter corresponding to the decreased fast corner. The slow corner timing parameter corresponds to a lowest value of an operating speed design window of the system-on-chip, and, the fast corner timing parameter corresponds to a highest value of the operating speed design window of the system-on-chip.

    摘要: A testing device uses an input signature register to conduct “at speed” testing of asynchronous circuit responses in an effort to determine the operability of a monitored circuit. Upon receiving an enable signal, the input signature register quickly measures, compresses, and transmits the tested circuit responses so that the responses can be compared with a set of anticipated responses to determine whether the circuit is functioning properly. The enabled input signature register, such as a MISR or a SISR, generates an output signature, which contains the compressed responses of the monitored circuit and helps the testing device analyze circuit performance.
