do DRC in each cell

jiunnweiyeh

Hi Sir,
I want to do a pattern shift check , and here is my code..
first, I want to check cell "DIE_PI1" , and compare 51/ 1 and 93/0.
and second , I want to check cell "DIE_CapRD" and compare 56/1 and 94/0......
But , Look like that have some wrong result that is not what I need.
it anythink I missed?

DIE=input(71,0)
shiftcheck=0.05
LayoutLibrary = RBA::Application::instance.main_window.current_view.active_cellview.name
puts "Library :  #{LayoutLibrary}"

LayerList.each { |n|
puts "========================"
compareCell=n[0]
layer1num=n[1]
layer1pur=n[2]
layer2num=n[3]
layer2pur=n[4]
currentcell = source.cell(compareCell)
puts "compare cellname:  #{compareCell}"

shiftcheckvalue=shiftcheck / 2
checkNonBump = centerpatternsize *2 + shiftcheck
checksize = (centerpatternsize / 2.0) - shiftcheck

layer1p=layer1.inside(DIE).middle.size(centerpatternsize.micron)

bumpshift = 1
end

rule=input(no_Bump)
if rule.is_empty?

end

if bumpmiss == 1 && bumpshift == 1
puts  "GA Shift OK"
end

if bumpmiss == 0 || bumpshift == 0
puts  "Check Result : NG,Check Bump_Shift / No_Bump Layer"
end

I think this is wrong:

currentcell = source.cell(compareCell)
puts "compare cellname:  #{compareCell}"
#########################################
layer1=currentcell.input(layer1num,layer1pur)
layer2=currentcell.input(layer2num,layer2pur)
...

Just switching the cell is sufficient:

cell(compareCell)
puts "compare cellname:  #{compareCell}"
#########################################
layer1=input(layer1num,layer1pur)
layer2=input(layer2num,layer2pur)
...

Hi Matthias,
Thanks a lot , It is workable!!
