Consult a skill for find cell placement

Jewell

Please consult everyone,

I want to achieve the following functions:

1; Open an any Top layout cell, assuming that there have been many calls to common cell A in this Top layout. Entering a common cell A, pressing a bindkey can list all common cell A called in the entire Top layout

2;After finding all common cells A, zoom in on one part of a common cell and click Next through the window to display the same points for browsing all common cells at the same magnification, in order to check if your edit meets all points and avoid errors such as LVS and DRC

Thank all .

  • Hi Jewel,

    Here is a pseudo code exemple on how to zoom in.

    Although, i do not remember how to make a blocking user input pause.

    You can imagine to highlight a net with lntAddTrace / lntRemoveAllTraces()  before /after zooming.

    This code will not work, but it will give you a starting point maybe.

    Regards,

    ;; copyleft ebecheto
    defun(xy2bBox  (xy @optional (d 0.5) ) let(( x y) x=car(xy) y=cadr(xy) list(list(x-d y-d) list(x+d y+d)) ))
    ;; xy point to a square bBox at this point
    ;;  +-----+
    ;;  |     |
    ;;  |  xy |
    ;;  |     |
    ;;  +-----+
    ;; return bounding Box around the point

    ;;inst=css()

    foreach(mapcar inst  setof(inst win~>cellView~>instances inst~>name==sprintf(nil "matgen[%d].c_col_pixel_cfg" C)))

    hiZoomIn(win=getCurrentWindow() xy2bBox(inst~>bBox 35))

    ;; Make a wait her somehow or save the image

    filename=sprintf(nil "%s%03d_%s.png" pattern i pixName);=> "Bzoom003.png"
hiWindowSaveImage(?target win ?path filename ?centralWidget t)

    )
