samsung asic iv std111 introduction this databook contains information about std111 0.25 m m 2.5v standard cell library for pure logic products developed by sec (samsung electronics corporation). the library basically contains various kinds of internal and i/o cells and soft-macros which are used for developing asic (application specific integrated circuit). it also includes a design kit helping designers to work in a workstation platform, and all sorts of design environments needed for an automatic chip design. there are seven chapters in this databook: chapter 1 introduction chapter 2 electrical characteristics chapter 3 internal macrocells chapter 4 input/output cells chapter 5 compiled macrocells chapter 6 pll in this databook each cell is followed by its ac electrical characteristics, and these characteristic values are almost equal when the corresponding cell is operated in a real chip. the purpose of this databook is to prevent any misuse or misapplication of std111 cell library by providing precise information about the cell list, electrical data, directions for use, and matters demanding special attention. if you want to get more information about digital cores and analog cores that are not included in this databook, access the samsung asic web site(http://www.intl.samsungsemi.com) or contact head office.
