  • Patent number: 8522188
    Abstract: 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.

  • Publication number: 20130086536
    Abstract: 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.

  • Patent number: 8156460
    Abstract: In a method of estimating a leakage current in a semiconductor device, a chip including a plurality of cells is divided into segments by a grid model. Spatial correlation is determined as spatial correlation between process parameters concerned with the leakage currents in each of the cells. A virtual cell leakage characteristic function of a cell is generated by arithmetically operating actual leakage characteristic functions. A segment leakage characteristic function of a segment is generated by arithmetically operating the virtual cell leakage characteristic functions of all cells in the segment. Then, a full chip leakage characteristic function of the chip is generated by statistically operating the segment leakage characteristic functions of all segments in the chip. Accordingly, computational loads of Wilkinson's method for generating the full chip leakage characteristic function can remarkably be reduced.
