    What are standard cell tracks ?

    hi,


    wat are tracks in std cells?
    what is meant my 9track,12track std cell?
    wat is d diff bt the above 2?
    which one is advantageous?

    12 track standard cell

    tracks mean routing resources

    standard cell 9 track

    track is the path in which wires can pass through

    routing tracks 12 track 9 track asic

    How many tracks means how big your cell is. normally, 8 lambda is one track if I am right. It depends on the technology.

    what is 9-track standard cell library

    Hi,

    one track is approximately the minimum spacing between metal1 and metal1 via in a technology node . Track is generally used as a unit to define the height of the std cell. a 12 track cell will be taller than a 9 track cell. a 12 track std cell will be taller , that means more metal1 routing space is available within the cell, hence cells will be faster. where as in a 9 track cell, the cell will be compact, but speed is less compared to 12 track.
    9track -> less area, less speed compared to 12 track
    12tarck -> more area, more speed compared to 9 trac

    Regards

    track in standard cell library

    hi can u eloborate on the relation between more metal 1 routing space availability and speed of the standard cell......................

    9/12 track standard cells

    Suppose you have a NAND gate. Now with same W/Ls of transitor if you make layout in 9 tracks and 12 tracks, then 12 track NAND gate layout would be somewhat in thinner but taller by 33.33%. Since it is taller that means there is more space horizontally available for routing over this 12 track cell compared to 9 track cell.

    standard cell and track

    hi praneshcn,

    the basic funda is simple , bigger cells has better driving capablity , than their equivalent normal cells . i.e they will be faster than their normal counter parts
