    placing welltap between every two cells Reply

    Hello,

    does anybody know how to place extra cell between any two cells while placing the design in Encounter. Let's say I have a welltap cell and I need to place it between every two cells in whole design. 

    Thank you in advance

    Jiri

    Hi JISO,

    If you want to place a well tap between 2 cells you can do but using of well taps is for avoiding the latch-up problem.

    so, for a particular design how many tap cells should be used and at what locations those taps should be located this will be estimated before placement of a design.

    so, if you want to place more taps than required leads to increasing the design density its again problem if the design density increeses.

    Hi Ganga,

    Thank you for your contribution to this topic. I know all the consequences of this decision. I am not the one who desided to go there but there is problem with latch-up and goal of this is to have tap inserted between all the cells. Ofcourse this will enlarge the design.

    I am still wondering how this should be done in encounter.
