CMOS VLSI design. What is standard Cell Library? Find out the Standard Cell Library for Master Slave J-K Flip Flop. Solution a standard cell library is the collection of logic gates such as AND,OR,INVERT,flipflops,latches,buffers.the main aspect of this cells is that they are of fixed height which allows them to be placed in rows making easy the process of automated digital layout.the cells are typically optimized full custom layouts,which minimize area and delays. standard cell library contains two main components: 1) library database -it contains views like layout,schematic,symbol,abstract and other logical views. Various information in cadence LEF format,synopsys milkyway format contain reduced information of cell layouts. 2) timing abstact-it is in liberty format whiich gives functional definitions ,timing,power and noise definitions for each cell. example is XOR gate which is formed from AND,OR and INVERT gates. master slave JK flipflop contains AND and INVERT logic gates. it contains master latch and slave latch..
