Traversing a schematic hierarchically

Hi Vivek,

Did you search for example code in this forum?

I found this code posted by Marcel previously:

;; traverse schematic hier 
;; and print all the instances that do not have any schematic view
;; most likely those are your primitives
;; cv - cv to scan

;; level - level down into hierarchy, used just to indent the printed lines.

procedure( mpTraverseHierSch( cv @optional (level 0) ) 
    foreach(inst cv->instances
        if( cview =  dbGetAnyInstSwitchMaster(inst "schematic") then
            mpTraverseHierSch(cview level+1)
        else
            ;; some pretty  printing
            for( i 1 level
                printf("    ")
            )
            printf("%s %s/%s in %L\n" 
                inst->name inst->libName inst->cellName
                list(cv->libName cv->cellName cv->viewName))
        )

    )
)

mpTraverseHierSch(topCellView)

Perhaps this is close to meeting your needs?  You would need to modify the function so that it accepted the library, cell and view name for the starting point, or add a simple wrapper, e.g. (not tested, I just typed this in...)

procedure(vrTraverseSchHier(@key lib cell (view "schematic"))
  when(forall(arg list(lib cell view) !blankstrp(arg))
    mpTraverseHierSch(dbOpenCellViewByType(lib cell view nil "r"))
  )
)

You would call your function using the keyword arguments, e.g. vrTraverseSchHier(?lib "myLib" ?cell "myCell" ?view "schematic")

Lawrence.
